This alloy combines good tensile and unusually high yield strength with good hardness and fair elongation to make it a popular gear, worm wheel, and bushing alloy. It is tough, stands up to overload, and resists “squashing" or "peening". It has good fatigue strength, good ductility, good rubbing resistance, and excellent corrosion resistance. It can be welded into complex assemblies and has good machinability.
It is ideal for medium to heavy gears, bushings, bearings, and worm wheel applications such as boom hoists and winches, rollers, and machine tool parts subject to shock or impact. Also used in marine propulsion, pickling equipment, pump and valve components, seals, wear rings, and wear-resistant parts.

Non-ferrous alloys are, literally, materials that are not iron-based. While others may provide non-ferrous materials of other materials, the MetalTek family of non-ferrous alloys are copper-based. In general, these materials deliver high strength, and excellent wear and corrosion resistance. They are often found in marine applications and also bushing, bearing, and gear environments.
Stainless steels owe their ability to resist corrosion primarily to the presence of a passive film on their surface. Chromium is chiefly responsible for formation of the passive film. Iron ceases to rust at approximately 12% chromium content and resistance to oxidizing corrosives increases rapidly with chromium content up to approximately 20%.
Specialty Alloys comprise a broad group of materials that deliver properties for more demanding applications, use more exotic or expensive materials, or require special processes to manufacture. Where standard materials may not offer desired performance, specialty alloys (including those that are modified further) may be a sensible selection.
