Scalping Aluminum Cold AMETEK Surface Vision

Scalpers remove surface impurities from aluminum ingots. They can also be used on edges to reduce trimming scrap. Accurate surface inspection systems can verify the quality of the scalping process. To create a high-quality surface for rolling, the broadest sides of a metal ingot are shaved by a machine with rotating blades, called a scalper.

Manufacturing flat rolled aluminium. - Aludium

Aludium’s manufacturing process starts with the definition of the composition alloy. The raw material can be supplied from Aludium’s own casting capabilities or from external, qualified suppliers. Every slab is thoroughly controlled to ensure the casting microstructure meets the defined quality level required for each application. The slabs are first cleaned (surface scalping and trimming of extremes) and then
