Tungsten and molybdenum alloys

Tungsten and molybdenum alloys

Supplier — AvekGlob Company — offers tungsten-molybdenum alloys at an affordable price from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Technical specifications

Tungsten-molybdenum alloys are highly resistant to high temperatures, corrosion resistance and strength, which is due to the high density of metals forming a stable metal matrix during melting. The considered alloys are also characterized by high erosion resistance. The main production method is powder metallurgy, where the components are sintered, and then rolled to the required dimensions and shape of the cross section.

Urgency of application

Main applications of tungsten-molybdenum alloys:

Aerospace, where products made from these alloy products are common due to low thermal expansion, high resistance to creep, corrosion resistance to hot gases;

Manufacture of glass and ceramics, where high thermal conductivity and electrical conductivity are used, low coefficient of thermal expansion, high corrosion resistance;

Automotive industry: alloys are used in the manufacture of automobile counterweights and balancers;

Chemical industry: corrosion resistance, durability, machinability and heat transfer, make tungsten-molybdenum alloys highly sought-after;

Metallurgy and heat treatment: these alloys are used in equipment intended for sintering, soldering, annealing and other heat treatment processes;

Manufacture of light sources and electrovacuum equipment.
