Electrical Contacts Material- Product Brief

The method ofpowder metallurgy is reliable and processable.Product list:

Instructions for use:

The advantages of using the chemical coating method to manufacture: Without poor oxide area, uniform distribution of oxide, stable electric performance Stable contact resistance, low ratio of electroerosion, and long electricity life.One of this series includes trace additive which can improve the displacement of electric arc and the performance of melting and welding. Moreover, it can prevent the concentration of the electric arc and the melting or welding property from decreasing, so that the
material can have an ideal surface and excellent non-fusibility.
The advantages of using the method powder sintering extrusion:The fibrous uniform distribution of Ni particle in longitudinal direction, be perpendicular to the contact working surface.Stable contact resistance, low ratio of electroerosion, and long electricity life. Apply in the field of low current, such as relays, contactors, circuit breakers, etc.
Ag and CAg
The products of Ag and CAg are produced by water and air atomization in our company, which is an advanced way to produce powder metallurgy products which have mucn more homogeneous structure and better performances than other products’ by other ways but atomization. Pure silver and fine silver can be provided in different shapes and sizes,including wire, strip, component etc..
In all of metal, the electrical conductivity and the thermal conductivity of silver are the best. Silver has not only the excellent properties of small and stable contact resistance and anti-oxidation, but also the good performance of erosion 28 ISO9001 ISO14001 OHSAS18001 Certificate resistance. It is the same with punily voltaic contactors, relays, low-press switches, thermoadjustors and electric irons.
To Improve the integrative performances of silver, some nickel(about0.15wt%)are added to the pure silver to make the silver particle diminished consumedly. Hardness and life time of CAg, therefore, increase a lot. Other properties, however, are almost no less than pure silver’s. Thus, applications of CAg are much wider than pure silver’s.
Ag Oxides of Rare Earth
Rare Earth Oxides fully make use of our country’s source advantage, and is an environmental material. FEPAC owns its fully intellectual property rights. Moreover, it also uses the chemical coating method to manufacture.
 AgCuO, AgZnO
Application field: under 10A~1000A and 24~600V’s current limit switch and leakage circuit breaker.
General Evaluation: high stability of its oxide, outstanding performance of electric/ heat conduction and melting/ welding.
