There are kinds of electrical contacts, LML mainly produce silver electrical contact rivets, dear customers,this article from LML Engineering Dep. will introduce something about electrical contacts and answer some questions,such as “what is electrical contacts”, “electrical contacts
Types” “how to choose right contact material for different application”...
First,according to the different shape,the electrical contacts have the following types:
Silver Electrical Contact Rivets
Silver Electrical Contact Tips disc
Silver Bimetal Electrical Contact Rivets
Button Silver Electrical Contacts
LML's material factory produce electric contact of silver (Ag) with ceramic material (SnO2, In2O3, ZnO, CuO) or silver (Ag) / Copper(Cu) with high melting-point metals (WC, W, Mo , Ni , C) .
The features of LML silver electrical contacts : high electric conductivity, good erosion-resistance and anti-welding, and using four integrated technologies : cold-bonding,
internal oxidation, powder metallurgy and brazed rivet.
To conform the Restriction of RoHS and WEEE ,LML successfully developed environmentally (Green) silver contact material and other precious material, to supply electric & electronic
plants for various appliances.
The contact material used For Electrical Contact Rivet
Some contact material we called Green Electric Contact Materials including Ag , AgCu , AgNi , AgSnO2 , AgSnO2In2O3 … …
About Ag(pure silver) ,The Composition is Ag 99.95 or Ag 99.85,Ni 0.15
About AgCu, we use Ag 80, Cu 20 or Ag 75, Cu 25
About AgNi,we usually use Ag 90, Ni 10 ; Ag 85, Ni 15
About AgSnO2, we usually use Ag 92, SnO2 8 ; Ag 90, SnO2 10
About AgSnO2In2O3 , we usually use Ag 92, SnO2In2O3 8 ; Ag 88, SnO2In2O3 12
Traditional Electrical Contact Materials is AgCdO,now we seldom use it.
The main Composition have 5 types, Ag 90, CdO 10 ; Ag 88, CdO 12 ; Ag 86, CdO 14 ; Ag 85, CdO 15 ; Ag 84, CdO 16
