Below is a list of Nickel Metal manufacturers from Hamden, Connecticut. Nickel metal is an element that is malleable, somewhat ferromagnetic, hard, and ductile, and a conductor of electricity and heat. The metal is silvery white and can come in a polished or brushed nickel surface. Nickel metal can also be produced in various forms, such as flakes, sheet, spheres, rods, powder, foil, wire, or mesh.
