CONNECTOR ALLOYS

Each new assignment will be approached by the connection designer with information on the intended mechanical qualities, operating environment, and life expectancy of the connector. His mission is to find a specific design that can be manufactured reliably and affordably. To achieve this, he must identify the copper alloy and temper that will allow the connector to be made, built, and utilised successfully for the duration of its planned life at the lowest possible cost.

What are connector alloys?

Connector alloys is a catch-all term used to describe a series of complex metal alloys that have; over a series of years been developed for the sole purpose of being used to manufacture complex connectors for the defense, aerospace, and electronics industries. They are typically comprised of a variety of special elements which when combined provide corrosion resistance, strength, machinability, and conductivity.

How are connector alloys manufactured?

The users and manufacturers of connector alloys require that the materials supplied have specialised chemical, mechanical and physical properties to meet the purpose of the item an individual is producing. The production of connectors generally apply some form of machining, stamping, cold- heading or other mechanical transformation. These operations require a suitable combination of machinability, formability, or cold-work ability. Industrial connectors for use in the fields of aerospace, defence, and electronics are machined from raw materials that begin as small diameter metal rods manufactured to extremely tight tolerances. Modern CNC machining techniques are then used to produce extremely accurate, sometimes very small parts which are then used in the manufacture of connectors which are made up of several different parts.

What does ILF offer?

ILF stocks a wide range of high-quality Copper, low alloyed Copper, Brass, and Bronzed alloys. These guarantee high electrical conductivity combined with optimal properties in tensile strength and mechanical processing. Our connector material range is used to manufacture pin and socket connectors, RF connectors, contact pins, and corrosion-resistant fiber optic connectors which can be used in the aerospace, telecommunications, IT, automotive, and consumer electronics sector.
