Heavily Load Flanged Sleeve Bushing In Construction Mining

Thrust washer manufactured from copper nickel tin alloys UNS C72900, equivalent to Toughmet. Inway Cu15Ni8Sn serves as a direct equivalent to Toughmet 3 and represents a proven solution with extensive testing to ensure full compliance with relevant specifications, helping high-end industries mitigate supply chain risks.

Inway CuNi9Sn6 has been engineered to address technical, economic, and ecological constraints for heavily loaded bearings in construction mining, automotive, and industrial applications.

Inway serves as an ideal substitute for steels, cast leaded bronze, manganese bronzes, and cast spinodal copper nickel tin alloys like C96900 CX105 and C96970 CX90, ensuring adequate fatigue strength.

Materials are available in two tempers:

Copper Nickel Tin spinodal alloys feature specific metallurgy enabling spinodal decomposition, providing a unique combination of material properties. High mechanical properties are achieved through hot working or combined hot and cold working processing, dramatically enhanced with final heat treatment controlling spinodal decomposition.

A threefold increase in yield strength over base metal is achieved after spinodal decomposition treatment. These heat-treated "spinodal alloys" excel as bearing and bushing materials due to high strength, low magnetic sensitivity, excellent machinability, and maximum corrosion resistance.

High surface resistance under impact loads, particularly in critical lubrication conditions, provides longer lifespan, higher reliability, and better construction flexibility compared to conventional bearing materials.

These materials have been approved by numerous OEMs or are undergoing qualification processes in highly demanding industries including Aerospace and Oil & Gas.

Actuation systems, friction bushings and bearings for primary and secondary flight controls, wheels and brakes, and various aircraft systems attachments. In landing gears, bushings and bearings operate under severe conditions with high loads and increasing hydraulic systems pressure.

Heavy mining equipment and vehicles including excavators, haul trucks, mining shovels, draglines, continuous miners, pivot bushings and bearings, tri-cone rock bit roller cones, reamers, HDD tools bushings, and thrust washers.

In mining equipment, bushings and bearings are highly stressed components operating in aggressive media with harsh minerals. Hardiall® CuNi15Sn8 and Hardiall Eco® CuNi9Sn6 demonstrate excellent lubricity, wear and galling resistance.

Hardiall Eco® CuNi9Sn6 is ideal for applications combining ecological and economical constraints with moderate to high load capacity, while Hardiall® CuNi15Sn8 serves highest mechanical properties requirements.

Onshore: Artificial lift sucker rods, valve guide couplings. Offshore: Subsea wellhead controls, manifold, mud pumps, LWD and MWD components, HDD tools, drill bits, bearings, bushings, thrust washers, ROV hydraulic connectors, valve components trim.

Hardiall® is specifically used in offshore subsea applications where increasing depths create challenges with high temperatures, high pressure, and aggressive media like sour environments.

Racing cars, passenger vehicles powertrain components (valve guides, plain bearings, bushings), braking and steering systems (brake caliper bushings, steering bushings).

HARDIALL® spinodal alloys provide high strength and hardness, excellent machinability, maximum corrosion resistance, and high wear resistance under high loads, especially in critical lubrication conditions. Compared to conventional materials, Hardiall® enhances design optimization with reduced mechanical clearances, boosting performance and reliability.

Additional developments in Defense, Industrial, Metallurgy, Renewable Energy, and Ship Building industries.

HARDIALL® spinodal alloys unlock potential for high-strength copper alloys, offering a technical and economical alternative to Beryllium Copper, Nickel-based Corrosion Resistant Alloys (CRAs), Titanium, Precipitation Hardening Steels, Stainless Steel, and Manganese Bronzes.

This material serves as the choice for design engineers solving challenges with stringent requirements and environments, particularly for performance friction bushings and bearing cages.

HARDIALL® benefits from fully integrated manufacturing processes and a global distribution network. Lebronze alloys internal processes include casting, hot and cold working stages, heat treatments, and non-destructive testing. Full integration ensures reactivity and complete traceability throughout the supply chain from major OEMs to local machine shops, supported by worldwide partners network.
