| High nickel, high cobalt iron alloy. A traditional metal-to- glass sealing alloy that offers a low coefficient of thermal expansion (CTE) similar to glass. Provides the hermeticity required for firmly bonding between metal and glass. Frequently used for hermetic enclosures or packages used to protect electronic or optical devices in aerospace, automotive, optical, optoelectronic, and telecommunication industries. Property values reported are typical for Kinetics' MIM products. Metal Injection Molding General Notes: Fine metal powders (generally <25 microns in diameter) are combined with a polymer binder system to form a feedstock suitable for injection molding. Kinetics' feedstock is compounded using specific binder and metal powder formulations to control consistency, quality, and dimensional repeatability of parts produced. While standard plastic injection molding machines and molds are used to produce MIM parts, due to the presence of the polymer binder in MIM feedstocks, mold cavities are designed approximately 20% larger than the final part size. Like plastics, MIM molds may have multiple cavities, inserts, slides, unscrewing cores, and hot runner systems. After molding, green parts are debound and sintered at temperatures up to 2,600°F. During debinding, the polymer binder breaks down and dissipates while the metal particles retain all of the molded features. The metal particles fuse together during sintering and the part shrinks approximately 20% to form a solid metal part. Information provided by Kinetics, Inc. |
