Astro Alloys, Inc. products

Astro Alloys offers a range of Kennametal Stellite cobalt thermal spray powders and coatings, engineered specifically for hard-facing applications. These cobalt-based alloys are designed to provide exceptional protection against various forms of wear including adhesive wear, abrasion, erosion, and contact fatigue, as well as thermal shock, cavitation, corrosion, and oxidation. Renowned for their durability, these coatings maintain impressive wear, galling, corrosion, and erosion resistance, even at elevated temperatures. The alloys are categorized into three major groups, with Tribaloy alloys featuring a hard inter-metallic Laves phase, providing extra toughness where lubrication is challenging. These properties make the coatings ideal for rigorous environments often encountered in industrial settings.

Astro Alloys Inc. offers a range of TAFA arc thermal spray systems, which are engineered to enhance simplicity, durability, and repeatability across various coating applications. These systems utilize a dual-wire feed mechanism into the gun where an electrical arc melts the wires. This molten material is then sprayed onto the substrate, ensuring even coating distribution and particle atomization. Notably, the TAFA Models 8830MHU and 8835MHU are specifically lauded for their high deposition efficiency and ability to create coatings with excellent bond strength and homogeneous microstructure. These models also include optional features like ArcJet attachments and different drive roll configurations. Another model, the TAFA Model BP-400, is particularly versatile, offering a lightweight and portable solution adaptable for both manual and robotic applications. These technologies cater to demanding industries such as aerospace, heavy equipment, and power generation, providing solutions for component restoration, corrosion resistance, and surface defect repair.

Astro Alloys Inc. specializes in supplying a wide range of TAFA thermal spray wires designed for arc spray applications. These wires comprise both traditional metal and complex cored compositions, providing tailored solutions for various technical needs. Engineered exclusively for thermal spray, the wires are subjected to stringent testing to ensure they offer the required tensile strength, hardness, and surface finish for reliable application. The advanced manufacturing process involves precise metallurgical composition and production controls to eliminate defects. Cored wire technology enables compositions that are not possible with solid wires, making them valuable for applications in aircraft engine repair and industrial wear protection. Designed for high-performance coatings, TAFA wires offer solutions for bond coats, dimensional restoration, and resistance to wear and corrosion, replacing traditional plasma coatings in various scenarios.
