How can we improve?

29 Products

Raw Materials

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments—all with material certificates for traceability

Steel

Strong, machinable, and weldable—all with material certificates for traceability

Plastic

A lightweight alternative to metal and glass

Rubber

Compresses and bounces back to shape; often used for sealing, cushioning, and shock absorbing

Tungsten

Our densest metal resists wear and heat to make end mills, heat shields, electrodes, and more

Ceramic

Hard and wear resistant, it also withstands corrosion and high temperatures

Brass

More machinable than copper and bronze—all with material certificates for traceability

Glass

Clear and highly heat and chemical resistant; often used in sights, lighting, and lab equipment

Titanium

The most corrosion-resistant metal we offer—all with material certificates for traceability

Nickel

An upgrade from stainless steel to withstand harsh chemicals and acids—all with material certificates for traceability
