The company is into manufacturing high-quality
iron powders.
Hoganas (India) is an Indo-Swedish
joint venture, which  commenced
commercial production in 1987. The Company
manufactures high-quality iron powders,
which finds application in the manufacture
of sintered components, low-hydrogen welding
electrodes and several chemical and metallurgical
industries.
The Company's collaborator Hoganas, Sweden,
holds a 51% equity stake in the company.
The Company uses the Hoganas process invented
and developed by its parent company, which
designed, installed and commissioned its
existing annealing plant. In 1992, it embarked
upon a backward integration project, which
entailed the acquisition of the water atomizing
plant of Mahindra Sintered Products, the
prime source of raw atomized powder. This
reduced dependence upon imports for its
raw material. After modernisation, productivity
has improved substantially in terms of both
quality and quantity.
The Company products find use in the following
business areas:
Sintered components : The largest
field of application for iron and metal
powders is component manufacture. Instead
of traditional fabrication techniques like
casting and machining, iron powder is compacted
under very high pressure in a die. The component
is then sintered (heat-treated) to give
it the requisite mechanical strength.
Welding : An admixture of iron powder
in welding electrodes can raise the quality
of the welded joint, while at the same time
giving more efficient welding. The amount
of weld obtained from a given quantity of
welding wire can be substantially increased,
in certain cases by up to 80 per cent.
Cold stream products : Coldstream's
mandate is to develop, produce and deliver
high-alloy powders that ensure high added
value, including application know-how. The
goal of development is to offer powder alternatives
which give the customer lowest total cost.
Soft Magnetic Composites : SMC
is a family of metal powders developed by
Höganäs. They are our answer to the development
needs of today's and tomorrow's electrical
machine designers and builders. SMC make
it possible to construct electrical machines
with 3-dimensional magnetic fields, achieving
increased design flexibility and power.
Chemical Metallurgical : Iron powder
has the ability to improve the properties
of numerous other products, such as those
of the manufacturing, pharmaceutical and
foodstuff industries.
Carrier cores : A number
of the carrier cores on the market are based
on ferrites, which can contain environment
heavy metals. Today, the force of legislation
and the public opinion demands greater environmental
responsibility. The company has answered
this demand by basing its carrier cores
on iron or magnetite, Fe304- a natural mineral.
By combining high-purity iron with special
organic additives, Höganäs has developed
soft magnetic materials that permit the
designing of electric motors with high torque
and low magnetic losses. These new composite
materials have been evaluated with excellent
results in various types of electric motors.
Moreover, the motors can be made smaller,
which is important since they are being
increasingly used for various functions
in passenger vehicles.
