Durability and low thermal expansion are the key advantages to the new nickel alloy, Invar-36.
Developed by Plymouth Extruded Shapes (Hall 3, Stand C12) it can be used in the manufacture of lay-up tools for the production of components from advanced composite materials, which are utilised in the manufacture of aircraft frames.
Invar-36 can be produced in many design shapes, including angles, hollow shapes, channels and tees. That means less wastage than there would be with the machined and welded tools manufactured from the traditional plate and bar materials. Manufacturing nickel-alloy in pre-formed shapes also helps to reduce cost, labour and materials. The material can be shaped because of the low co-efficient of thermal expansion that's used in its manufacture. That minimises the mismatch between the composite materials and allows for mould warping during the curing cycle. Plymouth Extruded Shapes even provides in-house stretch-straightening, making parts exceptionally flat and straight.
