Description:

non-ferrous metal bar, copper, high conductivity. Widely used, copper rod is a kind of non-ferrous metal processing bar, with good processing performance and high conductivity. Phosphorus copper is a copper-phosphorus alloy, theoretically speaking, is also a kind of bronze. Mainly used in welding industry. Difficult to process. Hard and brittle in nature. The distinction between the four kinds of copper alloys you mentioned can be judged in terms of properties / appearance, in addition to their composition: phosphor bronze is the purplish red appearance of the phosphor bronze, which is close to the purple (pure) copper color. Copper phosphate is extremely brittle and very difficult to process Bronze containing 3% tin and often added phosphorus, zinc, lead, etc. It is the earliest alloy used by human beings and has been used for about 4000 years. It is corrosion-resistant, wear-resistant, has better mechanical and technological properties, and can be welded and brazed well without sparking during impact. It is divided into processed tin bronze and cast tin bronze. The tin bronze used for pressure processing contains less than six pieces of tin, and the cast bronze contains 10 pieces of tin. The commonly used brands are QSn4-3, QSn4.4-2.5, QSn7-O2, ZQSn10, ZQSn5-2-5, ZQSN6-6-3, and so on. Tin bronze is a non-ferrous alloy with minimum casting shrinkage. It can be used to produce castings with complex shape, clear outline and low air tightness. Tin bronze is corrosion-resistant in the atmosphere, seawater, fresh water and steam, and is widely used in steam boilers and marine ship parts. Phosphorus-containing tin bronze has good mechanical properties and can be used as wear resistant parts and elastic parts of high precision working mother machine. Lead-containing tin bronze is often used as wear-resistant parts and sliding bearings. Zinc-containing tin bronze can be used as high gas tightness castings

Features:

 tin bronze: tin content is generally in the range of 314%, mainly used to make elastic components and wear-resistant parts. Phosphorus bronze: the addition of trace phosphorus to tin bronze increases the strength and hardness, corrosion resistance and wear resistance of the alloy. It can increase wear resistance, hardness, fluidity and processability. Tin bronze is a kind of non-ferrous metal alloy with the lowest casting shrinkage. It is used to produce castings with complex shape, clear outline and low air tightness. Tin bronze is very corrosion-resistant in air, sea water, fresh water and steam. Widely used in steam boilers and marine ship parts. Phosphorus-containing tin bronze has good mechanical properties and can be used as wear resistant parts and elastic parts of high precision working mother machine. Lead-containing tin bronze is often used as wear-resistant parts and sliding bearings. Zinc-containing tin bronze can be used as high gas-tightness castings.

Role:

phosphor bronze, similar to QSn6.5-0.1, has high fatigue strength, elasticity and wear resistance due to high phosphorus content, but it has hot brittleness during hot working, so it can only be processed under cold pressure.
