HPM® 400 is a Nickel-Copper alloy with excellent corrosion resistant characteristics in marine environments.
The alloy is readily formed from the annealed temper. It is easy to fabricate by conventional welding techniques.
Available Sizes:
HPM® 400 is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.050” (0.0127 mm to 1.27 mm) and widths up to 12.0” (304.8
mm). The material conforms to ASTM B127 and UNS N04400.
