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

Tungsten

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

Rubber

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

Brass

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

Ceramic

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

Aluminum

Lightweight, easy to machine, and corrosion resistant—all with material certificates for traceability

Material Handling

Ball Transfers

Install in arrays to create platforms for conveying, rotating, and positioning heavy objects
