How can we improve?

965 Products

Raw Materials

Bronze

Better wear resistance than copper and brass—all with material certificates for traceability

Copper

Our most conductive metal for electrical applications—all with material certificates for traceability

Tungsten

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

Fluid Handling

Tube and Tube Fittings

Tube and Tube Fittings

Typically more flexible than pipe for carrying liquids and gases in short runs around equipment

Fastening and Joining

Shims

Align and space components on shafts, or level machinery, cabinets, and doors
