ARCAP AP1D
CuNi25Zn11.5Pb1 · C79350
ARCAP AP1D is a copper-nickel-zinc rod alloy designed and produced by Lebronze alloys for parts made mainly by machining. Watchmakers and instrument makers use it for small non-magnetic parts that must hold their dimensions and resist corrosion.

GradeChemistryYield strengthChoose it when
ARCAP AP1DYou are hereCuNiZn550 MPaChoose it when the part is machined from rod and machinability comes first. For parts formed from strip, ARCAP AP1 and ARCAP AP1C are the family's forming grades.
ARCAP AP1CuNiZn530 MPaChoose it when your part is formed from annealed strip and does not call for a UNS grade. ARCAP AP1C covers UNS C79360 and harder tempers, ARCAP AP1D covers parts machined from rod.
ARCAP AP1CCuNiZn750 MPaChoose it when the drawing calls for UNS C79360, when you need hard or stress-relieved tempers, or when one grade must come as rod, strip and wire. ARCAP AP1D is the choice for heavily machined rod parts.
