Aluminum

Aluminum is difficult to polish, as it is soft and the melting temperature is low. Too high temperatures will change the lattice structure of the aluminum, which can have impacts on further processing of the aluminum. Therefore different strategies and aluminas have to be applied. Almatis offers varius grades to fullfil the customers needs.
