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.
