HIDURON 130 is one of the highest strength copper alloys available. Being a cupronickel, it has excellent resistance to corrosion by seawater and in marine and industrial atmospheres and it is highly resistant to crevice corrosion.

HIDURON 130 also has a very low magnetic permeability – it is virtually non-magnetic – and has 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.

HIDURON 130 contains about 14.5% nickel and is strengthened by additions of aluminium, iron and manganese. It is covered by the specifications DIN 2.1504 and DTD 900/4805 to which it can be supplied when required.

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.
