CONDUCTIVE, HIGH-STRENGTH BRUSHCAST® ALLOYS FOR DEMANDING APPLICATIONS 

Materion’s BrushCAST copper beryllium casting alloys provide many advantages in demanding commercial, industrial and aerospace applications. In addition to high strength and high conductivity, BrushCAST alloys offer hardness greater than many steels, but with thermal conductivity greater than aluminum.

Our copper beryllium casting alloys meet tough technical specifications with characteristics including good electrical conductivity, wear and galling resistance and excellent replication of cast detail. These properties allow casts to be made for plastic mold making, die cast plunger tips, non-sparking safety tools, parts for defense applications and undersea components.

Depending on alloy selection, BrushCAST alloys are available as casting ingots or master alloys in ingot and shot forms. 

Our BrushCAST casting alloys are available in the several chemistries, which are outlined below. The versions noted as CT indicate the addition of titanium, producing casting alloys with smaller material grains, improved machinability and polishability.

Download the BrushCAST datasheet for the following casting alloys:

• Alloy 165C / Alloy 165CT is characterized by high thermal and electrical conductivity, as well as higher elongation.
• Alloy 20C / Alloy 20CT offers higher strength and greater hardness than many steels along with thermal conductivity five times that of steel.
• Alloy 21C provides a good balance of strength and thermal and electrical conductivity.
• Alloy 275C / Alloy 275CT provides the highest hardness, yield and tensile strength of all BrushCAST alloys.
• Alloy 3C / Alloy 3CT offers the highest thermal conductivity and the highest electrical conductivity that has ten times the conductivity of steel.
