Powder Metallurgy is a continually and rapidly evolving technology embracing most metallic and alloy materials, and a wide variety of shapes.

Is the science of molding metals parts from metal powders to exact dimensions. The resultant product is equal to the parent metal and many times offers additional features. Often it´s natural porosity provides benefits of flow, oil retention or heat dissipation that broaden the designer’s scope.

When it is necessary to obtain combinations of properties, the mix of selected metal powders offers one product with a diversity of uses.  Metal powders are selected for size, shape and ultimate usage. They are blended with lubricants and subsequently molded in steel dies at pressures up to 100.000 PSI to get the compact of a desired shape.  The high precision forming capability of PM generates components with near net shape, intricate features and good dimensional precision pieces are often finished without the need of machining.  Pieces are bonded (sintered) at high temperatures in furnaces with controlled atmosphere to increase strength and alloy the material. In the case of high porosity metals, molds of heat-resistant materials are filled with the metals and gravity sintered to achieve the required strength. Subsequent sizing, machining or finishing are identical with that used on conventional methods.

Some advantages:

Economic advantages => Cost savings. Low scrap (over 95% the highest row material utilization). Low energy requirements, High volume in short lead-times.

Product advantages => many mechanical properties such as: Hardness, Elongation, Creep, Corrosion Resistance, Impact Strength, Tensile Strength, Fracture Toughness, Compressive Strength, Elasticity, Porosity, Ductility, etc…, are homogeneous and controlled through out the entire product.

Close dimensional tolerances and good surface finish.

The usage of non conventional mixtures gives unique properties attainable only by the PM route.
