Alloy Grade UNS: M-30C – Acid and Alkaline Resistant

  • Overview

    M-30C, also known as MTEK E, is a nickel-copper alloy specifically formulated for exceptional resistance to both acidic and alkaline environments. With a minimum of 60% nickel and up to 33% copper, along with a maximum of 0.5% aluminum, this alloy exhibits excellent corrosion resistance across a wide pH range. Its high nickel content contributes significantly to its ability to withstand aggressive chemicals and corrosive solutions. M-30C also possesses good tensile strength, making it suitable for applications where structural integrity is important. Furthermore, it is a weldable grade alloy, offering flexibility in fabrication and repair. This combination of corrosion resistance, strength, and weldability makes M-30C a valuable choice for demanding applications in chemical processing, pollution control, and other industries where resistance to both acids and alkalis is critical.

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%.

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.
