| OFHC commutator
copper shaped rod and bus bar |
The OFHC commutator
copper shaped bar and copper trolley bar have passed the
province-grade appraisal , it is a kind of the province-grade
new products of high and new techniques, The main technical
parameters of silver copper are equal to JB/T8987-1999
standard .The silver bearing copper alloy shaped bus bar's
main technical parameters are better than the parameters
of the copper alloy in Japan and Germany,its comprehensive
function is up to the 1990s international standard and
in leading place in China.
Chosing materials for the product is strict,its productive
technology is advanced,its quality is checked at each
level. The main raw material is No.1 electrolytic copper
plate , according to the necessary per cent of silver,
pure silver is put in to be smelted together to be the
alloy of silver and copper.ln the manufacturing process,the
method of two-layer cover deoxidation is used to free
oxygen,just the right amount of rare-earth metal grain
fine agent is put in and drawn up with the vacuum technique,and
they are rolled to be great out of shape a few times,etc.
Those new technologies are used to make the alloy line
materials with every kind of specifications.There are
some strong points in the product,as its oxygen content
is lowest,its hardness is high,it's crystallized to be
thick,its internal force is even, The silver bearing copper
alloy mechanical strength is high and electric conductivity
is better,its heat and corrosion resistance is good,but
its price is only half of the same kind of product abroad.ln
order to make its quality stable and reliable, and make
users feel satisfied and relieved, We has founded an advanced
material physical chemistry laboratory,the spectrometer
absorbing light with atom and the system of computer working
station .From the raw materials being chosen to the finished
product being out of the factory,following each level,all
the process are tested.
The OFHC silver bearing copper alloy has good function,its
price is lowest . silver copper alloy's application is
wide,it is a kind of ideal new metal material with high
function for the High-New technique products,as high-grade
miniature electrical machineries,microelectronics elements,aerospace
etc.And it's ideal material for the universal products,as
household appliances, auto motor fittings, electric tools
etc

| Our commutator strips, profiles
and wires offer higher softening temperature and improved
creep properties.JCcopper offers various silver bearing
copper grades that are based on oxygen-free copper. JCcopper's
excellent material consistency is crucial for the fabricator
who wants to improve the efficiency of his processes.
Material is available cut to any length according to your
requirement. We produce the oxygen-free silver bearing
copper alloy shaped bar according to client requirement.
Please send your drawing with chemical composition and
physical parameters .Our price is the lowest . Other specifications
and sizes are available upon request. Please contact us
