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.

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.

How manufacturers use various metals for matrix metal composites

Though it’s not a metal, adding straw into mud to make bricks that don’t crumble easily might represent the first composite material documented in history. Surprisingly, some currently standing mud-composite buildings have lasted for hundreds of years, demonstrating adobe’s clear superiority over mud or straw alone as a building material. Relying on similar principals of…

The Infiltration Process to Create Matrix Metal Composites

Metal Matrix Composites, often shortened to MMC, refer to composite materials formed from at least two parts. The properties of these composites improve the material’s properties to provide benefits for certain applications. Some examples might include very durable components for drill bits or strong, lightweight parts for aerospace and transportation. According to Science Direct, some…

Benefits of Alloying Ag with Copper Alloys

Copper use is numerous and widespread. From electrical wires to copper pipe fittings, industries around the world employ this metal for their operations. Typically, copper is not the sole metal used in applications. Other metals will be alloyed with this material to provide a wide range of properties and characteristics. Silver (Ag) is an element…
