AgNi series:AgNi material with 10-40% of high melting-point metal nickel has high electric conductivity, low contact resistance and little burning loss. This material has littleTransfer when connecting and breaking direct current. Agni material are widelyUsed in AC and DC low-voltage devices, such as relays, instruction switches,Can switches, assisting contactors. Instrument switches, optical control switches, temperature controller and washing machine timers.AgCdO series:AgCdO is the most used contact material at present. Cdo obviously increased theFusion resistance or cohesive resistance of the contacts at the moment of gettingThrough big current. The sublimation of CdO cools the contact surface, lowers theArc energy and extinguishes the arc. Therefore, AgCdO can meet the mainRequirements of low-voltage apparatus to contacts, such as arc burning resistanceAt big-current switching-on, low and stable contact resistance under various loadsAnd good arc extinguishing performance. Since CD pollutes the environment, it isSubstituted by other materials.AgSnO2 series (CD free) :This material is produced by dispersing SnO2 Oxidation in silver base produced byPowder method and keeps up superior electric conductivity with improved anti-arc,Anti-fusion, anti-abrasion. This material, as silver oxidation dispersed strengtheningType alloy dispersion, features that SnO2 is thermally stable and AnO2Is distributed fully on Ag Metrics as a high anti-arc, anti-fusion, anti-abrasionPre-oxidizer material. Especially, this material possesses excellent propertiesFor the use of relay and switch at heavy load area of DC.AgSnO2In2O3 series (CD free) :This is the superior material in the properties of anti-fusion and anti-abrasionUnder various load conditions because it is CD-free material, now one of the seriousEnvironmental issues, and it is produced by internal oxidization method alloyingAg-Sn alloy with many additive elements. This is used for AC and DC Load.AgCu series:Anti-discoloration decreases depending on the content of copper, while hardness andMechanical anti-abrasion increases. Contact strength is strong and it is not usableIf there is a sliding contact when it operates.
AWS E308L-16 is a super low carbon stainless steel electrode with titanium calcium type coating. As the carbon rate in the weld mental is no more than 0. 04% , it has good inter-crystalline corrosion
