What is billet?

Billet simply means a block of metal. Billet aluminium (alloy) stats off as a block of  alloy and every part we make must be carved from these blocks. We develop new parts through computer modelling and once these measurements are fed into our CNC machine, the cutting tools carve metal from the block  to create a perfect and accurate part every time.
