The lateral departure, in arc form, of an edge from linear straightness.
Leaded Phosphor Bronze Phosphor Bronze
Hard and strong cast and wrought Copper/Tin alloys with small, deliberate, Phosphorus additions.
Wrought alloys such as PB102 contain 4% to 8% Tin, whilst cast alloys contain 9% to 12% Tin.
Leaded Phosphor Bronzes, with Lead contents up to 20% ,are usually available only as castings – Examples are PB1 and SAE660.
Localised Corrosion
A general term for, often high rate, corrosion attack affecting restricted, specific, parts of the surface.
Surface marks caused by localised flow that appears on some alloys after light straining. They run parallel to the direction of maximum shear stress i.e. at 45° to the direction of the deforming stress.
