Detailed Description to the Processing Process of Contacts Materials
High voltage contacts can be made into different shapes by powder metallurgy (extrusion / sintering / infiltration).
From the raw material to the silver alloy electrical contact material, from the contact, the composite strip, the component production to the pre-sales after-sale service. Our company alloy has the ability to control the whole process of production and quality. In order to ensure the stability of the product quality, the key quality control points are controlled by means of various techniques and analytical tools.
Taking silver tin oxide as an example, the processing process of several processes is briefly introduced in this section.
Internal Oxidation Alloy
Characteristics
ØDuring internal oxidation, Sn is
difficult to oxidize completely
Powder Metallurgy
Characteristics
ØUneven distribution of SnO2 powder;
Ø Poor combination strength of Ag and SnO2, poor processing performance of materials;
ØThe density and resistance of the material can not reach the technological standard of internal oxidation of the alloy.
Ultrasonic
Chemical Coating
Characteristics
ØThe SnO2 powder is uniformly
distributed;
ØThere
is no incomplete oxidation of Sn in direct use of SnO2.
ØThe
bonding strength between Ag and SnO2 is good, and the processing performance of
the material is improved effectively;
ØThe
density and resistance of the material are the process reference for oxidation
method in the alloy.
