The bronze alloys from Termomecanica are a reference in the market for their quality, resulting in an optimal cost / benefit ratio for customers. By using copper as a base and tin as an alloying element, a highly resistant alloy called bronze is obtained, which has great resistance to corrosion and an ease of finishing that allows excellent polishing.

TM 23 BRONZE

Alloy developed and patented by Termomecanica that became a reference in the market, presents good resistance to corrosion, excellent antifriction quality, excellent machinability, ideal formability for bushings and / or bearings and controlled wear elements.

This material is used in the manufacture of water pumps, valve bodies, bushings, bearings, rings, hydraulic materials and accessories, coupling elements, wear plates, high-speed and high-pressure bearings, rolling bearings for rolling mills, gear mills, press bushes, friction bushes, components and / or parts that require resistance to corrosion, gears for locomotives fused with moderate pressure on the flanks of the teeth and situations in which availability of lubrication is small.

TM 620 BRONZE

This alloy has a higher relative hardness compared to TM 23 brass, in addition to good machinability, good resistance to corrosion related to salt water action, good properties for structural parts, good weldability and good impact resistance and absorption of energy.

It is often used in the production of piston rings, component valves, gear and/or bushings for heavy loads and low speeds and it is also applied in steam connections, expansion joints, screws, nuts, housings and pump rotors, condenser components, seat stems and parts resistant to pressure and temperature.

The chemical composition of the mechanical properties presented were extracted from the ASTM standard.

TM 23 BRONZE LAYERS

They present the best performance in the market, being destined to the market of sugarcane and produced with the TM 23 bronze, an exclusive alloy with a high content of lead (Pb). Lead is insoluble in solid bronze alloys, being isolated in the form of small modules in a ternary matrix of Cu-Sn-Zn. In the free space between the shaft and the bearing, lead is interposed between the shaft and the material that supports it, reducing wear and preventing or delaying clustering.
