Why Copper Castings Are Popular for Precision Mechanical Accessories

Copper castings stand out among non-ferrous castings due to unique physical properties of copper materials.The material has superior ductility and wear resistance,and will not easily deform or wear after frequent friction and assembly disassembly,extending the service cycle of the whole equipment set.Copper also has good electrical and thermal conductivity,so copper castings are widely used in parts requiring conductive and heat-conductive functions.

The casting process of copper castings puts forward higher requirements on temperature control,and strict temperature monitoring is needed in the melting and pouring link to reduce internal casting defects.The surface of finished copper castings can be polished,passivated and anti-oxidation treated to prevent surface oxidation and discoloration in long-term storage and use.

Copper castings are mostly used in key matching positions of alarm devices and lubrication oil pumps.Their tight casting structure ensures good sealing performance of assembled equipment,avoiding oil leakage and poor contact.Both standard size copper castings and special-shaped customized copper castings can be produced through mature casting processes to adapt to different industrial supporting standards.
