Hardiall® is available in two tempers: TX temper (solution annealed, wrought and spinodally hardened temper) and TS temper (solution annealed, cold finished and spinodally hardened temper) for even higher mechanical properties.
In landing gears, bushings and bearings are required to operate under severe conditions, they need to be lubricated and replaced frequently causing recurring maintenance downtimes.
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 alloys materials.
Hardiall® is ideal for applications where the load required exceeds the performance of copper-nickel-aluminum based alloys or where lubricity is critical and titanium cannot satisfy the Engineers requirements.
In mining equipment, bushings and bearings are highly solicited components. They need to be lubricated and replaced frequently implying recurrent production downtimes and maintenance man hours.
Hardiall® is used in excavators, mining trucks and longwall shearers. For such mining vehicles, Hardiall® demonstrates excellent lubricity, wear and galling resistance making it the ideal material for bushings and bearings.
For these applications, Hardiall® outperforms steel and manganese bronze by increasing the durability, the reliability and the lubrication cycles of highly solicited bushings and bearings.
Hardiall is also used in onshore oil pumps as 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. Thus providing a reduction of failures and hence maintenance downtimes.
For these applications Lebronze alloys integrated supply chain is able to propose ready-to-use products.
Landing gear attachments, Engine and Pylon attachments, Flight control mechanisms, Doors and Hatches. Many other developments in Ship Building, Subsea and Chemical industries.
Depending on applications, it can replace advantageously Beryllium Copper, Nickel based Corrosion Resistant Alloys (CRAs), Titanium, Precipitation Hardening Steels, Stainless Steel and Manganese Bronzes
Lebronze alloys is willing to expand the applications of high strength alloys with this new CuNiSn product, along with existing Aluminum Bronzes and age hardening CuNiSi alloys:
