Iron Powder

SLM is one of the few companies who have pioneered the production of Sponge Iron Powder. These powders are used in:
Applications:

• Powder metallurgy
• Welding Industry
• Chemical Industry,
• Alloying Industries

Main characteristics of these powders are:

• High Internal porosity
• High surface area
• Controlled particle size distribution
• Good compressibility & Green strength
• Apparent Density which can be varied from 2.4 – 3.0

Various grades of Iron Powder

• Welding Grade
• Flame Cutting Grade
• Alloying Grade
• Sintered Part Manufacturing Grade
• Chemical Grade
