Applications
Hardiall® is increasingly being used in a wide range of industries where thanks to the unique combination of properties it is helping to prevent failures and ensure a longer lifespan compared to traditional materials. Industries include motorsport, aerospace, oil & gas, construction, mining & heavy transport, automotive, defence, space, marine, power transmission and renewable energy.
Aerospace
Aerospace Applications
Hardiall®is used within the aerospace industry thanks to its outstanding physical and mechanical properties in many varied components. Lebronze alloys has developed a full range of Hardiall®products matching the stringent needs of the aerospace industry.
Bushings and Bearings for Landing Gear
In landing gear, bushings and bearings operate under severe conditions. They need to be lubricated and replaced frequently resulting in recurring maintenance downtime.
To reduce maintenance costs, Hardiall® is used for such applications as it demonstrates excellent lubricity, wear, and galling resistance, thus providing a longer service life and an improved total cost of ownership (TCO) compared to other copper and non-copper alloy materials.
Hardiall® is ideal for applications where the load required exceeds the performance of copper- nickel-aluminium based alloys or where lubricity is critical and titanium cannot satisfy the engineer’s requirements.
Other Applications
- Landing gear attachments
- Engine and pylon attachments
- Flight control mechanisms
- Doors and hatches
Oil & Gas
Oil & Gas Applications
Hardiall® is used within the oil & gas industry thanks to its outstanding physical and mechanical properties in many varied components. Lebronze alloys has developed a full range of Hardiall® products to match the stringent demands of the oil & gas industry.
Bushings & Bearings
Hardiall® is used in bushings and bearings for drilling components. For such applications, Hardiall demonstrates outstanding wear, corrosion, temperature and pressure resistance, thus providing a longer service life and a better total cost of ownership (TCO) compared to beryllium copper, as well as some nickel or cobalt based alloys.
Hardiall®can be used in both offshore and onshore systems and in vertical or directional drilling products.
Couplings for Onshore Production Systems
Hardiall® is also used in onshore oil pumps for sucker rod and valve rod guide bushing couplings. In such applications, where stainless steel is generally used, Hardiall®demonstrates excellent resistance to metal-to-metal wear, providing a reduction of failures.
Other Applications
- Wellhead controls
- Manifold pumps
- Valves trim
- Mud pumps
- Motor & turbine bearings
- Christmas trees
- Drilling tool bits
- Drilling tool trust washers
Mining & Construction
Mining & Construction Applications
Hardiall® is used within the mining industry thanks to its outstanding physical and mechanical properties in many varied components. Lebronze alloys has developed a full range of Hardiall® products to match the stringent demands of the mining industry.
Bushes & Bearings
In mining equipment, bushings and bearings are subject to extreme conditions and need to be lubricated and replaced frequently, which results in downtime and maintenance man-hours.
Hardiall® is used in excavators, mining trucks and longwall shearers, where its performance characteristics - lubricity, wear and galling resistance - make it the ideal material for bushings and bearings. In such applications, Hardiall® outperforms steel and manganese bronze due to its superior durability and reliability, reducing downtime and maintenance cost.
Other Applications
- Heavy mining equipment
- Tri cone reamers
- Horizontal & vertical drilling tools
- Thrust washers

Escalators & Lifts
- Bushings
- Bearings
- Gear drives
- Worm wheels
- Wheel Shafts
Hardiall® is used in bushings, bearings, worm & worm wheels and wheel shafts. For such applications, Hardiall® demonstrates outstanding mechanical strength and wear, corrosion and temperature resistance. Hardiall® contributes to longer service life and a better total cost of ownership (TCO) compared to steels, aluminium and phosphor bronzes.
Bushings & Bearings for Heavy Metallurgical Equipment
Hardiall® is suitable for wear related parts like bushings and bearings in heavy metallurgical equipment like extrusion presses, rolling and drawing mills. In such applications where hardening steels, carbon steels or phosphor bronzes are generally used, Hardiall® demonstrates excellent resistance to metal-to-metal wear, thus providing fewer failures and hence reducing costly maintenance downtime.
Other Applications
High pressure equipment including:
- Seals
- Valves
- Nozzles
- Waterjet nozzles
