Frequently Asked Questions

Manganese bronze is a strong, corrosion-resistant bronze alloy made from copper, zinc, manganese, and iron, used in marine and heavy-duty applications.

Used in ship propellers, winches, gears, valve stems, and other parts exposed to high loads and saltwater environments.

Manganese bronze offers excellent strength, wear resistance, and corrosion resistance, making it ideal for mechanical and marine applications.

Yes, it performs well in marine environments due to its corrosion resistance and durability under load-bearing conditions.

Non-Ferrous

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 Steel Parts

Stainless Steel

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%.
Petrochemical Fittings

Specialty Alloys

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.
