Mahavir Metal Corporation

We are engaged in offering HEATING Wire to the clients.

Typical applications for Kanthal A-1 are electrical heating elements in high-temperature furnaces for heat treatment, ceramics, glass, steel, and electronics industries.

• High performance
• High specific resistance
• Excellent strength

• Nichrome is used in the explosives and fireworks industry as a bridge wire in electric ignition systems, such as electric matches and model rocket igniters
• Industrial and hobby hot wire foam cutters use nichrome wire
• Nichrome wire is commonly used in ceramic as an internal support structure to help some elements of clay sculptures hold their shape while they are still soft. Nichrome wire is used for its ability to withstand the high temperatures that occur when clay work is fired in a kiln
• Nichrome wire can be used as an alternative to the platinum wire for flame testing by colouring the non-luminous part of a flame to detect cations such as sodium, potassium, copper, calcium etc
• The alloy tends to be expensive due to its high nickel content. Distributor pricing is typically indexed to commodity market prices for nickel
• Other areas of usage include motorcycle silencers, in certain areas in the microbiological lab apparatus, and as the heating element of plastic extruders by the RepRap 3D printing community
• For heating, resistance wire must be stable in air when hot. Nichrome wire forms a protective layer of chromium oxide

Some resistance heating alloys and pure nickel are available as stranded wire.

• High performance
• High specific resistance
• Excellent strength

Molybdenum Rod, a refractory metal is widely used as an alloying element. Due to its good thermal and electrical conductivity, high melting point and excellent strength at elevated temperatures, molybdenum can be used for various applications in its pure form. In addition, molybdenum has low thermal expansion coefficient. It has to be protected by a suitable coating to withstand temperatures above 500°C under an oxidizing environment.

The following table shows the chemical composition of molybdenum.

• ASTM B386
• ASTM B387

• Machining molybdenum is similar to that of cast iron. Molybdenum tends to tear if positive feeds are not employed

Molybdenum can be efficiently formed while bending in a transverse direction or against rolling or grain direction. The workpiece can be heated before forming to avoid cracking.

Molybdenum can be welded using electron beam methods and other resistance methods in helium or argon atmosphere.

Annealing of molybdenum can be performed at 1149°C (2100°F).

The following are the major applications of molybdenum:

• Heating elements in furnaces
• Filament supports in electric lamps
• Heat shields
• Hearth trays, plates and racks
• Missile and aircraft parts
• Boring bars
• Thermocouples
• Nuclear energy applications

Kanthal Strip A-1 is a ferritic iron-chromium-aluminium alloy (FeCrAl alloy) for use at temperatures up to 1400°C (2550°F). The alloy is characterized by high resistivity and very good oxidation resistance.
