About Copper, Brass, and Bronze

Porous Mold-Quality Metapor Aluminum

Create molds for vacuum-forming and thermoforming applications. Metapor aluminum is porous to let air and moisture escape, which prevents bubbles and blemishes.

Easy-to-Form Pure 1000 Series
Aluminum Sheets and Bars

Made of 1000 series aluminum which is 99% pure, this aluminum offers superior formability, corrosion resistance, and electrical conductivity. It's frequently fabricated into raceways, decorative trim, and other parts where strength and hardness are not required.

Easy-to-Machine MIC6 Cast Aluminum Sheets and Bars

MIC6 is cast from a high-strength 7000-series aluminum, then stress relieved to maintain dimensional stability during high-speed machining.

Easy-to-Machine MIC6 Cast Aluminum Discs

MIC6 is cast from a high-strength 7000-series aluminum, then stress relieved to maintain dimensional stability during high-speed machining.

Easy-to-Machine Cast Aluminum for Tool and Jig Plates

Made of 5083 aluminum, these cast tool and jig plates are more corrosion resistant and respond better to anodizing than MIC6. This material is comparable to Alca 5 and ATP 5.

Lightweight Aluminum Foam

Air is injected into the casting of this aluminum to reduce weight and create a crater-like appearance. This foam is often used for sound insulation and architectural facades.

Cast Iron

Easy-to-Machine Gray Cast Iron Tubes

Gray cast iron machines faster with less wear on cutting tools than most types of steel. It's often fabricated into gears, pulleys, rollers, and bushings.

Oversized Easy-to-Machine
Gray Cast Iron Rods and Discs

An oversized diameter allows for finishing to your exact requirements.

Oversized Tight-Tolerance
Easy-to-Machine Gray Cast Iron Rods

Precision ground to a tight diameter tolerance, these rods are ready for turning in your lathe.

Easy-to-Machine Gray Cast Iron Sheets and Bars

Gray cast iron machines faster with less wear on cutting tools than most types of steel. It's often fabricated into gears, pulleys, and bushings.

Impact-Resistant Ductile Cast Iron Rods and Discs

Ductile cast iron is strong, resilient, and able to handle repeated stress without breaking.

Impact-Resistant Ductile Cast Iron Bars

Ductile cast iron is strong, resilient, and able to handle repeated stress without breaking.

Easy-to-Machine Impact-Resistant
Ductile Cast Iron Bars

Easier to machine without cracking than other impact-resistant ductile cast iron bars, these cast iron bars contain a high amount of ferrite. Use them to make cylinder and die blocks, rotary tables, and rail spacers.

Easy-to-Machine Impact-Resistant
Ductile Cast Iron Rods

With a high amount of ferrite, these cast iron rods are easier to machine without cracking than other impact-resistant ductile cast iron rods. Use them to create bushings, gears, pulleys, and pistons.

Bearing Bronze

932 Bearing Bronze Tubes

Offering excellent antifriction qualities, 932 bronze also offers good strength and wear resistance. It's also known as SAE 660 and is often used for bearings, bushings, and thrust washers.

Oversized 932 Bearing Bronze Rods

Diameter is oversized to allow for finishing.

Tight-Tolerance 932 Bearing Bronze Rods

These rods are precision ground for a tight diameter tolerance of ±0.0005".

Oversized 932 Bearing Bronze Bars

The thickness and width are oversized to allow for finishing.

Tight-Tolerance 932 Bearing Bronze Bars

Precision ground on the top and bottom, these bars have a tight thickness tolerance of ±0.002".

Oversized Weldable 954 Bearing Bronze Bars

Thickness and width are oversized to allow for finishing.

Tight-Tolerance Weldable 954 Bearing Bronze Bars

These bars are precision ground on the top and bottom for a tight thickness tolerance of ±0.002".

Weldable 954 Bearing Bronze Rods

954 bronze contains a minimum of 10% aluminum for strength and weldability. It is also known as aluminum bronze. It's widely used for bearings, bushings, valve bodies, and worm gears.

Weldable 954 Bearing Bronze Tubes

954 bronze contains a minimum of 10% aluminum for strength and weldability. It is also known as aluminum bronze. It's widely used for bearings, bushings, valve bodies, and worm gears. The strength of this material increases with heat treating.

Easy-to-Machine 936 Bearing Bronze Rods

An easier-to-machine alternative to 932 bronze, 936 also has better corrosion resistance. It's also called modified SAE 64.

Easy-to-Machine 936 Bearing Bronze Tubes

An easier-to-machine alternative to 932 bronze, 936 also has better corrosion resistance. It's also called modified SAE 64.

Easy-to-Machine 936 Bearing Bronze Bars

An easier-to-machine alternative to 932 bronze, 936 also has better corrosion resistance. It's also called modified SAE 64.

Ultra-Wear-Resistant AMPCO® 18 Bearing Bronze

AMPCO® 18 is a premium aluminum-bronze alloy that combines strength with superior wear resistance.

High-Strength 863 Bearing Bronze Tubes

Frequently called manganese brass, 863 bronze can handle heavy loads and high speeds when properly lubricated.

High-Strength 863 Bearing Bronze Rods

Frequently called manganese brass, 863 bronze can handle heavy loads and high speeds when properly lubricated.

Tight-Tolerance High-Strength 863 Bearing Bronze Bars

Frequently called manganese brass, 863 bronze can handle heavy loads and high speeds when properly lubricated. These bars are a higher-strength alternative to tight-tolerance 954 bearing bronze bars.

High-Strength Machinable 955 Bronze

For a good combination of strength, machinability, and weldability, choose 955 bronze.

Lead Discs

Use these cast-lead discs as spacers, washers, and counterbalances.
