Aiman Metals stands out as a leading manufacturer and supplier of Cobalt Alloy 6B Bars and Rods, proudly based in Kuala Lumpur, Malaysia. Renowned for providing high-performance materials designed for tough environments, Aiman Metals specializes in precision-engineered cobalt alloy products that serve a variety of industries, including aerospace, power generation, chemical processing, and marine applications. The company guarantees that all Cobalt Alloy 6B products adhere to stringent international quality standards, delivering exceptional strength, wear resistance, and corrosion resistance. With advanced manufacturing techniques and a strong focus on customer satisfaction, Aiman Metals has earned a reputation as a reliable source for specialty metal solutions throughout Malaysia and Southeast Asia.
Cobalt Alloy 6B, often referred to as Stellite 6B, is primarily made up of cobalt (about 60%), along with notable amounts of chromium (28–32%), tungsten (3.5–5%), and a small percentage of carbon (0.9–1.4%). This distinctive composition provides outstanding wear resistance, particularly against galling and metal-to-metal sliding. In terms of mechanical properties, Cobalt Alloy 6B Bars and Rods boast a tensile strength of around 965 MPa, a yield strength of about 517 MPa, and hardness levels ranging from 33 to 43 HRC, depending on how they are processed. The alloy retains its strength and stability even at high temperatures, making it an excellent choice for extreme service conditions that involve friction, heat, and corrosion.

Welding processes suitable for Cobalt Alloy 6B Bar include TIG (Tungsten Inert Gas), MIG (Metal Inert Gas), and resistance welding. Preheating and post-weld heat treatment are often required for optimal results.
Yes, Cobalt Alloy 6B Bar can be welded, but it requires careful control of heat and filler material to avoid cracking or weakening. Preheating and post-weld heat treatment are often recommended.
Cobalt Alloy 6B rods are available in various sizes, typically ranging from 0.125" to 6" in diameter. Common finishes include cold-drawn, hot-rolled, and polished for enhanced surface quality.
Cobalt Alloy 6B Bars and Rods find extensive use in industries that demand remarkable wear and corrosion resistance in challenging conditions. Typical applications include valve stems, pump sleeves, cutting tools, bearings, bushings, and wear plates. In the aerospace and power generation fields, it’s utilized in turbine components and engine parts due to its ability to endure high temperatures without compromising mechanical integrity. The alloy also excels in chemical plants and marine settings, where resistance to acidic and chloride-rich environments is crucial. Its superior metallurgical stability makes it a top choice for these demanding applications.
