Cast sheet with excellent machining properties |
Alca Plus is a precision cast sheet intended for applications where high surface quality, flatness and low residual stress is required. The sheet has a smooth structure and is free from containments and porosity. The sheet is suitable for machining, with small shavings/granules/particles/chips. Alca Plus can be used when flatness and dimensional stability is required. It is supplied face-machined with foil on one side. Typical fields of application - Packing machines
- Structures in which higher strength is required
Main advantages for Alca Plus - Free from tension
- Low weight
- Smooth flatness tolerance
- Good machining qualities
- Good thermal conductivity
- Varied application
- Free from contaminants and porosity
