Cobalt Based Alloy, commonly known by the brand name Stellite, are a family of high performance alloys primarily composed of cobalt combined with chromium and other elements such as tungsten, carbon, and nickel. Teamco provides API 6A valve castings, such as cage and wear sleeve of the choke valves, in these alloys highly valued for their exceptional strength, wear resistance, corrosion resistance, and high-temperature stability, making them ideal for applications in demanding environments. By knowing the material feature of versatility, Teamco has the capability to fine-tune properties of cobalt-based alloys for specific applications in industries such as aerospace and energy.

1. Wear Resistance: Cobalt-based alloys are incredibly durable and resistant to wear, abrasion, and mechanical stress, which is why they are widely used in cutting tools, valve seats, and other components that undergo constant friction and mechanical strain.
2. Corrosion Resistance: Thanks to their high chromium content, cobalt-based alloys exhibit excellent resistance to corrosion, particularly in aggressive environments such as acids, seawater, or high-temperature steam, making them suitable for chemical processing, marine, and other harsh environments.
3. High-Temperature Stability: These alloys maintain their strength and resist oxidation at elevated temperatures. This makes them ideal for components exposed to extreme heat, such as turbine blades and aerospace parts.
4. Hardness and Toughness: The alloy is extremely hard, which makes it effective for use in wear-resistant coatings and cutting tools. Despite its hardness, it remains tough and resistant to cracking, ensuring long-lasting performance in critical applications.

To eliminate casting trials and improve casting quality, Teamco utilizes process simulation tool which allows Teamco find the best counterpoise between casting quality and the production costs before creating physical prototypes for customers. From tooling die design, creations of wax and shell molds, metal liquid pouring, heat treatment and sand blasting, to QC inspection then the final casting, multiple variants determine to the casting quality. Teamco has experienced teams work closely with customer from the first stage when receive customers’ drawings. Adequate communications bring to satisfied customers.

Yes, Teamco can customize your Stellite castings to meet your specific designs or performance requirements.

1. Customized Materials for Your Specific Needs
We understand that the right material is key to performance of your parts. We can tailor the alloy compositions to match your exact specifications and desired mechanical properties, such as wear/ corrosion resistance and high-temperature performance based on your applications.
2. Collaborative Design Support
With expertise, we work directly with customers from beginning. For intricate designs that require high accuracy and a smooth surface and when part sizes fit, investment casting will be selected to create the high quality parts. Through implementing the simulation tool and comprehensive communications with customers, the castings will be produced by the optimized patterns. This collaborative approach leads to stable and long-term partnership.
3. Precision Machining for Perfect Fit
After finishing the castings, we provide CNC machining to fine-tune parts to meet exact specifications. To have smooth surface, we provide grinding and polishing. If you have demand of parts assembly, Teamco is capable of providing threading and tapping for sub-assembly. These procedures make sure your parts are not only functional but also ready for seamless integration into your products or system.
4. Heat Treatment and Surface Treatment to Enhance Durability
Specific heat treatment processes such as annealing or quenching enhance the mechanical properties of castings. To achieve required appearance and durability, we provide nitriding, shot peening, plating or coating to strengthen surface hardness or performance of corrosion-resistance.
5. Rigorous Quality Control to Let Customers Satisfied
We have comprehensive quality control process, material testing on strength and hardness ensures parts performance as expected, dimensional accuracy let parts meet needed measurements and non-destructive testing to check for internal defects and ensure structural integrity. With our rigorous quality control, customers can trust that every part will meet the highest standards, giving them confidence in such product development.
