Copper Based Binders for Oil, Gas & Mining Bits

4537D Binder Alloy

Copper Based Binder Alloys for Drill Bit Manufacturing

PDC Matrix Drill Bit Binder Alloys

Featuring Copper-based Binder Alloys enhanced with Nickel for Geothermal, Mining, Oil & Gas, Water Well drilling and horizontal applications. Our Copper Binder is an integral part of bits that are cast into a bit body with tungsten carbide matrix powder.

Belmont is the oldest and largest manufacturer of specifically engineered PDC Matrix Binder alloys for worldwide production of Drill Bits for Oil and Gas Drilling.

For over four decades, Belmont Metals Inc. has been instrumental in bringing a high quality, broad range of binder alloys to the oil and gas industry where applications blend tungsten carbide powders and impregnated diamonds for use in Matrix Bore Drilling bits, PDC (Polycrystalline Diamond Compacts) drill bits, core bits and a variety of other wear resistant applications.

Our Belmont Binder alloy 4537D is suitable as a standard infiltrant for Matrix (PDC) drill bits and as described as MF53 or 53MB in numerous US Patents, has a nominal composition, of 52.7 weight percent copper. 24.0 weight percent manganese, 15.0 weight percent nickel. 8.0 weight percent zinc, 0.15 weight percent boron, and 0.15 weight percent silicon with traces of lead, tin and iron.

This is an early design that Belmont has been producing for the Gas and Oil Drilling Industry for almost 50 years. It is still extensively used as a matrix for hard composites and continues to perform satisfactorily. The industry is constantly trying to further the performance of the matrices available by improving and refining hard composites used in an oil well drill bit. We can work with you on developing samples of other formulas if you provide us with non-proprietary chemistries. By supplying R&D bit quantities (> 60 lb.) to test your formula for improved properties, you can determine if the new properties increase impact strength, hardens, transverse rupture strength, erosion resistance and /or abrasion resistance. We have offered this service to many of the top bit manufacturers to help them design new formulas.
