Uses of Copper Powders

Copper Powder uses

This is a simple guideline for selecting copper powder products based on the application.

Bearings - CU165 and CU151 are recommended for blending with tin for the production of bronze self-lubricating bearings. More Details

Structural Parts -CU165, CU151, CU201 and CU301 are admixed with iron powder (2-10%)to improve strength and mechanical properties. These powders are also used to produce bronze and other alloy structural components.

Injection Molding - CU635 is specifically designed for parts produced using MIM.

Friction Components - CU151 is used for aircraft and other braking systems. It is also used for automotive and industrial “friction” components and applications.

Electrical Parts -CU185E is the industry standard for yielding high strength parts with excellent conductivity. Additionally CU635 offers high purity and is specifically designed for injection molded parts.

Carbon Brushes - CU41 is engineered for carbon brush tamping applications.

Abrasive Wheels - CU165, CU151, CU201 and CU301 are used as a matrix-bonding material for diamond and other abrasive wheels and cutting tools.

Chemical Formulations - CU165, CU151, CU185E, CU101, CU201 and  CU301 are widely used as catalysts in chemical formulations and for the production of copper compounds.

Thick/Thin Films - CU7005F is used for conductive coatings and conductive inks.
