Grade Polyamide Imide (GPIM) is a thermoplastic, thermosetting polymer which produces a high tensile strength, low density, and excellent electrical and thermal conductivity.

Grade Polyamide Imide (GPIM) is a thermoplastic, thermosetting polymer which produces high tensile strength, low density, and excellent electrical and thermal conductivity. The term GPIM can be used for both fine and thick sheets of aluminum and tin. It is often mixed with other polymers and materials to increase the strength and texture. This increases the cost and weight as well as making it difficult to cut because it imparts a grainy appearance. It is also difficult to machine because it requires additional material to form the wrap around layer. It is used in nearly all industries including aerospace, automobiles, and electronics.

 

The reason it has been used widely and successfully for mechanical applications is that the wire can be machined with low heat, high tolerance, and high strength. Many manufacturers have come up with special tools to work on aluminum. These tools use a rotating block of metal that is heated using electricity and then rotating forces it against a particular aluminum wire to make a shearing force. This creates a shearing of the aluminum wire. This is the basis of all popular wire gauges such as crimping, tab, spring, etc. Another use for Grade Polyamide Imide is in the production of almost alloys.

 

Alloys are made of many different elements. Copper, nickel, cobalt, and even titanium are used but there are some metals which are too soft or too hard to be used as an alloy. Grade Polyamide Imide Aluminum wire  can be used as the basis of various alloys including magnesium, tin, copper, brass, and aluminum. It can also be used as the base metal for stainless steel wire and soldered wire.
