Alloy Grade UNS: C97600 High Nickel-Leaded Bronze Alloy

  • Overview

    C97600 is a high-nickel, leaded bronze alloy that stands out for its distinctive silvery-grey appearance, often leading to it being called "nickel silver" despite containing no actual silver. This alloy is formulated with a significant nickel content, which contributes to its enhanced corrosion resistance, making it suitable for challenging environments where exposure to corrosive elements is a concern. The addition of lead improves its machinability, allowing for efficient and precise fabrication of components. C97600 is known for its ability to maintain its mechanical properties at moderately elevated temperatures, making it suitable for applications where both corrosion resistance and moderate heat resistance are required.

  • Typical Uses

    This 20% nickel silver alloy meets sanitary requirements for milk pump components and other parts for food handling equipment. It's also used for valve and pump components, fittings, and marine applications.

Frequently Asked Questions

Nickel-silver alloys are copper-based alloys with nickel and zinc that mimic the appearance of silver while providing strength and corrosion resistance.

No, nickel-silver contains no actual silver. Its name comes from its silvery appearance, not its composition.

Nickel-silver has moderate electrical conductivity—lower than pure copper but suitable for resistors, switches, and decorative electronics.

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.
