Looking for an Alloy C-276 Distributor? Contact James Duva Inc.

Alloys have a number of industrial uses. From food preparation equipment to power generators, alloys increase the durability of a number of machine parts. Alloy C-276 contains Tungsten which plays a unique role, as it increases an item’s ability to resist corrosion, improves toughness, and allows metals to endure extremes in temperatures. C276 is known universally as the most corrosion resistant material available today.

When you need a metal to resist corrosion and increase your machine’s durability, consider investing in alloy C-276.

The Benefits of Alloy C-276

Alloy C-276 is a nickel-molybdenum-chromium alloy mixed with tungsten. This alloy has an excellent corrosive resistance capacity and withstands pitting and stress cracking. Alloy C-276 has a variety of uses in industries including:

  • Waste and Chemical Processing
  • Pollution Control
  • Paper Operations
  • Food Preparation

As a highly weldable alloy, alloy C-276 has a variety of applications for your company.
