Matrix PDC bits are produced from composite materials made up of tungsten carbide powders and copper binder alloys that are metallurgically bonded with an infiltration process.

A Matrix Bit is designed to maximize hardness, resistance to abrasion and erosion. It is capable of withstanding relatively high compressive loads, but, compared with steel, has low resistance to impact loads. It performs well in higher speed applications.

Belmont Metals Inc. is the oldest and largest manufacturer of specifically engineered Matrix Binder alloys for worldwide production of down hole Drill Bits for Oil & Gas Drilling and the Mineral industries for horizontal drilling.

For over four decades, Belmont has been

instrumental in bringing a, broad range of high

performance Copper 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 most popular 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, made up of

Copper, Manganese, Nickel, & Zinc. This alloy is the

earliest of designs that Belmont has produced for the

Drilling Industry. It is still extensively used as a matrix

binder for hard composites and continues to perform

satisfactorily.

Copper Binder Alloys for Matrix PDC Drill Bits

Featuring Copper-based Binder Alloys enhanced with Nickel for Geothermal, Mining, Oil & Gas,

Mineral or Water Well drilling and for horizontal applications. Our Copper Binder is an integral

part of bits that are cast into a bit body with tungsten carbide matrix powder.

We also supply binders containing Tin, when Zinc is not workable in the factory.

The second most popular Binder is our 4785E alloy. For companies that cannot work with Zinc, we recommend this alloy, which has very similar properties when a spiral test is used for infiltration comparison.

The Drilling and Mining Industries are constantly working to further the performance of their Bits with new raw materials available. It becomes an economic asset when a company can improve and refine their hard composite drill bits used in an oil well or natural gas or mineral deposit.

We can work with your Scientists, Metallurgists, Engineers and R&D team when developing samples of new formulas if we are provided the (non-proprietary) chemistries.

By supplying your team with R&D quantities (< 15 lb.) to test new formulas for improved performance, they can quickly and economically determine if the new properties increase impact strength, hardness, transverse rupture strength, erosion resistance and /or abrasion resistance. We have offered this service to many of the top bit manufacturers around the world, helping them to design new products for demanding applications.
