• High corrosion resistance
  
• Excellent biocompatibility
  
• High tensile strength
  

Applications of Titanium

Titanium’s versatility makes it an ideal material for industries requiring high performance under extreme conditions.

Common applications include:

• Aerospace components: Turbine blades, airframes, and landing gear
  
• Medical implants: Hip joints, dental implants, and bone plates
  
• Chemical processing equipment: Heat exchangers and reactors
  
• Marine industry: Submarine parts and offshore oil platforms

What is Carbonyl Iron?

Properties of Carbonyl Iron

Carbonyl iron is a highly pure form of iron created through the thermal decomposition of iron pentacarbonyl. It features fine spherical particles, high surface area, and excellent magnetic properties.

Key Properties:

• High purity (typically >99.5%)
  
• Uniform particle size (micron or sub-micron scale)
  
• Superior magnetic permeability
  
• Low coercivity
  

Applications of Carbonyl Iron

Thanks to its magnetic and absorptive capabilities, carbonyl iron is used in both industrial and high-tech sectors.
