Hiduron 130 (Hidurax Special)

Hiduron^® 130 is a high-strength cupronickel supplied in the hot worked condition. Aluminium is the alloys key strengthening element through the formation of finely dispersed ϒ’ nickel aluminium precipitate, strengthening the alloy in a similar way to Alloy K500. As these precipitates are formed through a carefully controlled forging process, naturally aged during cooling, no further heat treatment is necessary, making it one of the highest strength copper alloys commercially available.

Being a cupronickel, Hiduron^® 130 has excellent resistance to corrosion by seawater, marine and industrial atmospheres as well as being highly resistant to crevice corrosion. It has a very low magnetic permeability, it is virtually non-magnetic, and it has a higher modulus of elasticity than is normally associated with copper alloys. All these properties are achieved without heat treatment and are combined with good machinability and the ability to take an excellent finish.

The major use of Hiduron^® 130 is in subsea hydraulic and electrical connectors such as flying lead connectors for stab plates. It is also used in naval winches, seawater valves and marine engineering generally. Additionally, it is applied in the aerospace industry for heavily stressed airframe components. Other applications include a variety of mechanical engineering and hydraulics systems amongst which are valve seat inserts and thrust washers for high performance internal combustion engines. It is covered by the specifications DIN 2.1504 and DTD 900/4805 to which it can be supplied when required.

Langley Alloys stocks Hiduron^® 130 as round bars from ½”-8” (12.7-203.2mm) diameter, and it can be supplied as bespoke forgings and blocks.
