Stainless Steel 17-4 PH polished optical mirrors

Superpolished Stainless Steel Optics and Mirrors

Superpolished metal surfaces approaching 5 Angstrom Ra finish, without using polished electroless nickel plating are now possible for use as mirrors. Valley's process of optically polishing these pure metal substrates and wafers enables materials such as 304SS, 316SS, 430SS and 17-4 PH (Custom 630) Stainless Steel, to be used as mirrors.

Physical properties of 17-4 PH Stainless Steel which are important for critical applications include:

Other super polished metal materials include Copper, Molybdenum, Brass, Aluminum and Nickel coated metals. Please call or e-mail for more details, or for a quotation per your specifications.
