ONE-Different Purposes:
1. Purpose of brass: Brass is often used in the manufacturing of valves, water pipes, connecting pipes for internal and external air conditioning units, and radiators.
2. Purpose of tin bronze: Tin bronze is a non-ferrous metal alloy with the smallest casting shrinkage, used to produce castings with complex shapes, clear contours, and low air tightness requirements. Tin bronze is highly corrosion-resistant in the atmosphere, seawater, fresh water, and steam, and is widely used in steam boilers and ship parts.
3. Purposes of copper: mainly used for making electrical equipment such as generators, busbars, cables, switchgear, transformers, and thermal conductivity equipment such as heat exchangers, pipelines, and flat collectors for solar heating devices.
TWO- Different Characteristics:
1. Characteristics of brass: Brass has strong wear resistance.
2. Characteristics of tin bronze: Adding lead to tin bronze can improve its machinability and wear resistance, while adding zinc can improve its casting performance. This alloy has high mechanical properties, wear reduction performance, and corrosion resistance, is easy to machine, has good brazing and welding performance, low shrinkage coefficient, and is non magnetic.
3. The characteristics of red copper: it has good conductivity and thermal conductivity, excellent plasticity, and is easy to be processed by hot pressing and cold pressing.
THREE-Different Chemical Composition:
1. Overview of Brass: Brass is an alloy composed of copper and zinc. Brass composed of copper and zinc is called ordinary brass. If it is composed of multiple alloys of two or more elements, it is called special brass.
2. Overview of tin bronze: Bronze with tin as the main alloying element.
3. Overview of Red Copper: Red copper, also known as red copper, is a simple substance of copper, named after its purple red color. Various properties can be found in copper. Red copper is industrial pure copper, with a melting point of 1083 ℃, no allosteric transformation, and a relative density of 8.9, which is five times that of magnesium. The mass of the same volume is about 15% heavier than ordinary steel.
FOUR-Know More About Copper, Brass, Bronze
Pure copper is a rose red metal with a purple color after the formation of a copper oxide film on the surface. Therefore, industrial pure copper is often referred to as purple copper or electrolytic copper. The density is 8-9g/cm3, and the melting point is 1083°C. Pure copper has good conductivity and is widely used in the manufacturing of wires, cables, brushes, etc; Good thermal conductivity, commonly used to manufacture magnetic instruments and meters that require protection against magnetic interference, such as compasses and aviation instruments; Excellent plasticity, easy to hot press and cold press processing, can be made into copper materials such as pipes, bars, wires, strips, plates, foils, etc.
Brass is an alloy of copper and zinc. The simplest brass is a copper zinc binary alloy, known as simple brass or ordinary brass. Changing the zinc content in brass can yield brass with different mechanical properties. The higher the zinc content in brass, the higher its strength and slightly lower its plasticity. The zinc content of brass used in industry does not exceed 45%, and a higher zinc content will lead to brittleness and deterioration of alloy properties.
Tin Bronze is the earliest alloy used in history, originally referring to bronze. It is called bronze because of its bluish gray color. Tin bronze has high mechanical properties, good corrosion resistance, friction reduction, and good casting performance; Low sensitivity to overheating and gases, good welding performance, no ferromagnetism, and low shrinkage coefficient. Tin bronze has higher corrosion resistance than brass in atmosphere, seawater, fresh water, and steam.
