    Different types of Plastic Material Avaialble

    The aluminium alloy has a low density but relatively high strength and can be processed into a variety of shapes. Its plasticity is excellent and it can match or exceed that of high-quality steel. Comparatively to steel, it is widely used in industry because of its high electrical conductivity, thermal conductivity, and corrosion resistance.

    Some aluminium alloys can obtain excellent mechanical properties, physical properties and corrosion resistance after heat treatment. Hard aluminium alloy belongs to the AI-Cu-Mg series, usually contains a small amount, and is enhanced by heat treatment. Hardness is high, but plasticity is poor.

    In the super aluminium alloy Al-1-Al-Al-O system, heat treatment can strengthen the material. It is the highest strength aluminium alloy at room temperature, but it has poor corrosion resistance and softens quickly at high temperatures. Wrought aluminium alloy is mainly an alloy of aluminium-aluminium alloy. It has a variety of elements, less content, good thermoplasticity, and is suitable for forging.

    Alloys derived from aluminium have excellent properties including processing, welding, corrosion resistance, toughness, high toughness, no deformation, easy polishing, no defects, and fantastic oxidation properties.

    The material is moderately strong, has good corrosion resistance, is weldable, and has good process performance (easy to be extruded). Scope of application: building windows, curtain walls, industrial equipment, frame accessories, solar energy frames, etc.

    There are two types of brass: ordinary brass and special brass. Brass is highly plastic, corrosion-resistant, deformable, and castable, and has a substantial industrial application value. According to the different chemical compositions, brass can be divided into two categories: ordinary brass and special brass. The so-called ordinary brass is a binary alloy of copper and zinc.

    The copper-zinc alloy can be divided into ordinary brass and special brass based on the elements added for better strength, corrosion resistance, and casting performance. The elements aluminium, iron, silicon, manganese, nickel, and others are added for better strength, corrosion resistance, and casting performance. Therefore, copper alloys composed of two or more elements are called special brass.

    Ordinary brass is composed of copper and zinc. According to the difference in zinc content, it can be divided into single-phase brass and dual-phase brass, but the zinc content cannot exceed 45%, otherwise, the material will become brittle and cannot be used.

    Special brass: Lead, tin, aluminium, and other alloying elements are frequently added to ordinary brass to create special brass. Lead brass, tin brass, and aluminium brass are the popular names for special brass. The purpose of adding alloying elements. Its main purpose is to increase tensile strength and improve processing performance.

    Red copper is pure copper, also known as red copper. Due to its excellent electrical and thermal conductivity, copper is widely used in the electrical industry and precision processing industries. The biggest advantage and performance of copper is its good electrical conductivity, second only to silver, but the price of copper is much cheaper than silver. Red copper has become the most important part of the electrical industry.

    High-purity copper is the primary condition for use in the electrical industry, and the purity must be higher than 99.95%. As long as a very small amount of impurities are mixed, the conductivity of the product copper will be greatly reduced, and the oxygen content of copper will also have a great influence on the conductivity. Impurities like phosphorus, arsenic, aluminium, lead, and antimony should be avoided in most cases. This kind of high-purity copper can only be obtained by electrolysis using original copper as the positive electrode, pure copper as the negative electrode, and sulfuric acid solution as the electrolyte. During the electrolysis process, the original copper on the positive electrode is melted and ionized, and pure copper ions are adsorbed on the negative electrode to obtain the pure copper we need.

    Purposes of copper: wires, cables, brushes, EDM copper, generators, bus bars, switch cabinets, transformers, heat exchangers, pipelines, flat plate collectors for solar heating devices, etc.

    Steel is an iron-carbon alloy. We usually call it steel. The carbon content of the material must not exceed 1.7% to ensure its toughness and shape. In addition to iron and carbon, other elements of steel include silicon, manganese, sulfur, and phosphorus. Other components will make the steel performance different.

    Both steel and iron are iron-based iron-carbon alloys, but due to the difference in carbon content, the state and structure of iron-carbon alloys are also different at different temperatures. Iron has poor formability, is not easy to deform, and has poor weldability. These properties of steel are very good, especially when a certain amount of alloying elements are added to steel, there will be some special properties, such as high strength, resistance to wear, heat, corrosion, etc.

    After ordinary steel is refined and other alloying elements are added, widely used steels with different properties can be produced, such as fatigue resistance, heat resistance, impact resistance, wear resistance, corrosion resistance, high polishing, etc. These high-quality steels are widely used in machinery parts, injection mold steel, stamping mold steel, aerospace, tools, automobiles, home appliances and other industries.

    In order to improve the performance of steel, we usually use heat treatment, stress treatment, quenching and tempering treatment, surface coating and other methods.

    Plastic is a polymer, and its main component is a synthetic resin. In addition, add some specific purpose additives as needed, such as plasticizers that can improve plasticity, anti-ageing agents that prevent plastics from ageing, and so on.

    Polymers may have a large relative molecular weight, but their compositions are not complex and their structures follow certain rules. They are made by the polymerization of small molecules, such as polyethene plastics, which are made by the polymerization of ethylene molecules. When polyethene plastic is heated to a certain temperature range, it starts to soften until it melts into a flowing liquid. The melted polyethene plastic becomes solid after cooling and then melts into liquid after heating. This phenomenon is called thermoplasticity.

    Polyethene, polyvinyl chloride and polypropylene are all thermoplastics. A thermosetting plastic, such as phenolic resin, will no longer be able to be softened and molded after processing, but it can be softened and molded when heated in the manufacturing process.

    Plastic is a poor conductor of heat, which has the effect of silencing and damping. Plastic hardness, tensile strength, elongation and impact strength. Due to its small specific gravity and high strength, plastic has high specific strength.

    Plastic parts are widely used in various fields of life, such as household appliances, instrumentation, wires and cables, construction equipment, communication electronics, automotive industry, aerospace, daily hardware, etc.

    Our commonly used titanium alloys are composed of titanium, aluminium, tin, vanadium, and niobium, and different elements form different properties.

    The main excellent characteristics of titanium are described as follows:

    Low density and high specific strength: Titanium has a higher density than aluminium but is lower than steel, copper and nickel, but the strength is on top of the metal.

    Good corrosion resistance and heat resistance. It is possible to use the titanium alloy at a temperature of 600°C for a long time.

    Low-temperature resistance: Titanium alloys Ti-al-2, Ti- 2-o and Ti alloys are low-temperature titanium alloys, whose strength increases with decreasing temperature, but the plasticity changes little. In cryogenic environments, it exhibits good plasticity and toughness at temperatures as low as 196-253°C, avoids cold brittleness common in metals, and is an ideal material for storage tanks and containers.

    The tensile strength is close to its yield strength: the titanium material has a higher yield strength ratio (tensile strength/yield strength) during the forming process, indicating that its plastic deformation is poor. As a result of titanium’s high modulus of elasticity compared to its yield limit, it has an incredibly flexible forming process.

    Better heat transfer performance: Although the thermal conductivity of titanium is lower than that of carbon steel and copper because titanium has excellent corrosion resistance, the thickness can be greatly reduced, and the surface heat resistance and steam reduce the thermal resistance, so there is no junction on the surface. By reducing thermal resistance, fouling can significantly improve titanium’s heat transfer capabilities.

    Alloys made from titanium have excellent physical properties that make them a preferred material in the aerospace, aviation, marine biomedicine, and automotive industries.
