Mechanical properties of  CuFe1.5P0.18Co0.8Sn0.6 (Olin 195)

In the mill annealed condition. i.e. precipitation hardened to have a yield strength of 450 MPa. Alloy C19500 can be readily cold formed by bending. shallow stamping or deep drawing. However. only moderate stretching should be attempted. in the cold rolled tempers. a generous bending radius is desirable and parts should be designed to avoid bends parallel to the rolling direction when maximum strength is required. The alloy can be hot worked in the temperature range 650 to 980 °C.

The alloy can be joined by the inert-gas shielded metallic-arc process and by resistance welding using the seam or butt welding procedures. It has excellent solderability.

Alloy 195 has a machinability rating of 18 where free-cutting brass equals 100. In general. the most satisfactory machined surface on copper is obtained by means of high cutting speeds combined with light cuts. For turning and similar operations. speeds of about 40 to 60 m per minute may be adopted but these speeds must be reduced when employing heavy cuts. With tungsten carbide tools. considerably higher speeds can be used. Tools are commonly used with about 15 degree front clearance and 25 degree top rake. The included angle of the cutting tool must be increased for heavy work. The lubricant employed should be varied with the type of work. For heavy cuts at slow speeds. mineral oils or blended lard and mineral oils are preferable; for lighter cuts at higher speeds. emulsions are favored. Degreasing of soiled metal followed by cleaning in a dilute sulfuric acid solution will remove surface oxidation resulting from atmospheric exposure or controlled atmospheric annealing. Heavy oxide films or stains are removed by the same brightening solutions used for copper.
