200 nickel rods are over 98% pure, so they offer corrosion resistance along with good formability, weldability, and electrical conductivity. They're often used in food-processing equipment and chemical shipping drums.

From marine hardware to chemical-processing equipment, 400 nickel rods are widely used for their strength, weldability, and formability. Comparable to Monel, this nickel-copper alloy will stand up to highly corrosive environments, such as those involving salt water, sulfuric acid, and alkalies.

Even in temperatures up to 2000° F, Alloy X nickel rods offer good strength and weldability, along with excellent oxidation resistance. They're often used for components in gas turbine engines and furnaces. This material is equivalent to Inconel HX and Hastelloy X.

C-276 nickel has excellent corrosion resistance against chemicals, including nitric acid, sulfuric acid, and hydrochloric acid.

This nickel-chromium, often called Chromel C, provides effortless formability. Use it for heating elements, resistance windings, and hot-wire cutters.

Because Invar 36 holds its size and shape when temperatures rise, these nickel-iron alloy rods are the go-to material when dimensional stability is required. They are commonly used when precision is a priority, such as for scientific instruments and optical devices.

Bend this wire and it will hold its shape until you heat it. It is commonly used in automotive switches and latches.
