Copper Powder
for Friction Products
Friction products include break
pads and clutch disks used in automobiles, commercial vehicles, aircraft,
motorcycles, trains and off-road vehicles, as well as many other industrial
machines. Brake pads or drum brake linings help stop a moving vehicle, while
clutches are used to initiate movement and cause a smooth acceleration of the
vehicles. Break pads and clutch disks are generally known as friction products.
Copper powder is used as a component of friction products to reduce wear and
prevent scoring. The percentage of copper powder in friction products is usually
less than 20%. Since copper powder acts as a lubricant, excess amount of copper
powder will reduce the friction. Production of friction products is usually by
compacting and sintering method or by resin bonding method.
Friction products may be made in
two different methods.
Sintered Friction Products
Applications of these materials
include brakes and clutches. They can consist of a mixture of metal powders
including copper, tin, bronze, brass, nickel, iron, zinc and lead, along with a
range of friction modifiers such as abrasives and solid lubricant. When
sintered, the resultant metal matrix material achieves the desired balance of
mechanical / frictional properties, heat conductivity, wear and corrosion
resistance, low noise level and high temperature performance.
Organic Based Friction Products
Metal powders are usually added to
organic based (non-sintered) friction products to increase heat conductivity,
alter wear properties, provide smoother braking action and reduce brake squeal.
ChemicalStore.com provides many grades of copper, tin, bronze, brass and nickel
to meet the needs of both segments of the Friction Products Industry.
