| 简介 |
For electric contact alloy the present invention according to, (Cd) cadmium weight ratio : 20% hereinafter, tin (Sn) : 2.0% hereinafter, nickel (Ni) : 1.0% hereinafter, is the remaining silver (Ag), other consists of unavoidable impurities. Wherein, preferably said compositions may be included is of rare earth metal less than 0.1%. And, is rare earth metal is rare earth (misch metal) misch metal made of metal is. Furthermore, the (Sc) scandium [...] , lanthanum (La), cerium (Ce), hafnium (Hf), palladium (Pd) yttrium (Y), neodymium (Nd) 1 selected from the group consisting of one or 2 species is or more mixtures.
According to the present invention the, cadmium heightening the content of the reducing [...] by adding and instead process recursive virtual machine instructions, Ad-Cd based alloy in the production casting on the bent up unit of the CdO produced during the oxidation process the so as to fine the metal oxide, fine crystal grain can be to promote proliferation. The (Cd) cadmium it is a scenery quality server returns an alloy Ag-CdO reduce the amount of addition of even if the cadmium content of the existing method Ag-CdO based alloy with an intensity of auto with [...] and my arc characteristic equal to or or more performance which can show manufacture of contact obtained Ag-CdO rotation is carried out, the amount. |
