Brass: Brass is an alloy composed of copper and zinc.
If it is only brass composed of copper and zinc, it is called ordinary brass.
If it is a variety of Alloys composed of more than two elements, it is called special brass.
Such as copper alloy composed of lead, tin, manganese, nickel, lead, iron and silicon. Brass has strong wear resistance.
Brass is often used to make valves, water pipes, air conditioners, internal and external connection pipes and radiators.
Phosphor bronze: phosphor bronze is the earliest alloy in the history of metal casting. It is an alloy that adds tin or lead to pure copper. Containing 2% ~ 8% tin, 0. 1% ~ 0. 4% phosphorus, the rest is copper alloy. Bronze has high strength and low melting point (
25% tin smelting bronze, the melting point will be reduced to 800 ° C. Pure copper (Red copper)The melting point is 1083 ° C).
Bronze has good casting property, wear resistance and stable chemical properties.
Bronze has the characteristics of low melting point, high hardness, strong plasticity, wear resistance, corrosion resistance, bright color, etc. It is mainly used as wear-resistant parts and elastic components.
