Inquiry (采购产品): Bell metal hardner We are casting a 80% Cu, 20% Sn alloy and would like to make it harder, as cast. Can you suggest an additive, Chrome or Nickel? Any help would be appreciated, thanks. **** Hidden Message ***** Jay Hitchings 19335 Company: Comanche Technologies LLC E-mail: jayrhitchings@msn.com **** Hidden Message ***** jayrhitchings@msn.com
