Size Range of Cobalt Alloy Rods
Our Cobalt Alloy Rods come in versatile dimensions, with extensive customization options:
- Diameter: 5 mm to 500 mm (0.201 to 4 inches)
- Length: Standard lengths up to 6 meters, extendable upon request
- Width/Thickness: Flat bars from 10 mm to 120 mm wide, thickness adjustable
- Custom Options: Precision-cut sizes and shapes for specialized projects
This flexibility allows our Cobalt Alloy Bars to meet the exact requirements of industries ranging from medical to heavy engineering.
Types: Forms, Processes, and Finishes
Cobalt Alloy Rods are available in various forms, crafted through advanced processes and finished to perfection:
- Forms: Round Bar, Flat Bar, Square Bar, Hex Bar, Forged Rods
- Processes: Hot forging, casting, powder metallurgy, cold working, precision machining
- Surface Treatments: Polished (Ra12.5), ground, pickled, or as-cast finishes
For example, a polished Round Bar enhances aesthetics and reduces friction, while forged rods offer superior strength for high-stress applications.

Frequently Asked Questions
Q:What are cobalt rods for?
A:Cobalt alloy rods, like Stellite, are used in cutting tools, aerospace components, and medical implants (e.g., hip replacements) due to their wear resistance, high strength, and corrosion resistance.
Q:Is stellite a cobalt alloy?
A:Yes, Stellite is a cobalt-based alloy rod, typically containing chromium and tungsten, known for its exceptional hardness and resistance to wear and corrosion in high-temperature environments.
Q:Is cobalt rust proof?
A:Cobalt alloy rods are highly rust-resistant due to their chromium content, forming a protective oxide layer. They perform well in seawater and acidic conditions but may corrode in highly oxidizing environments.
Q:Is cobalt chrome stronger than titanium?
A:Cobalt-chrome alloy rods often match or exceed titanium in wear resistance and hardness, especially in load-bearing applications like prosthetics, though titanium offers a better strength-to-weight ratio.
Q:Why is cobalt so special?
A:Cobalt alloy rods are special for their unique combination of high temperature strength, wear resistance, and corrosion resistance, making them ideal for harsh industrial and medical applications where durability is critical.
Q:Is cobalt magnetic?
A:Yes, cobalt alloy rods are magnetic, particularly in their pure form or certain alloys like cobalt-chrome. This property is useful in applications requiring magnetic properties, though it varies by alloy composition.
