High strength heavy load friction wear resistance

Mining industry

Lebronze alloys has a long history producing high strength materials and components for demanding mechanical and hydraulic applications, our high performance materials offering the required heavy load, fatigue, friction wear resistance at low speed rotations.

Lebronze alloys offers multiples materials solutions for various application in heavy vehicles hydraulics systems, attachments linkages hydraulic toolings as well as internal combution eingines for the various demanding applications within Mining, Construction, Quarrying, Forestry and Agricultural.
We offer materials and components solution to every challenge from cost effective High Tensile Brasses Manganese Bronze  to Nickel Aluminum Bronze with medium high srength, good friction, wear galling resistance and well suited for medium high working loads to Copper Nickel Silicon Chromium alloys and spinodal Copper Nickel Tin alloys with outstanding behaviour towards friction wear even with reduced lubrification galling and corrosion resistance to salt, coal dust, silica and other minerals various the highest working loads.
Thanks to their high properties they contribute to an extreme longer lifespan compared to traditional material usued minimizing unpredicted downtime and maintenance.

Use cases : Heavy Vehicles and Equipment, Pivot Bushings, Plain Bearings, Thrust Washers, Hydraulic Rock Hammer, Breaker floating bushings, Hydraulic Axial Pump, Piston Shoe, Plate Turbocharger, Axial Thrust Washer ,Floating and Semi Floating Bearings
