| Application areas | Hardiall® can be an alternative to Beryllium Copper for some applications. It is environment friendly, being Beryllium-free, Lead-free, and recyclable. Aerospace: friction bushings and bearings. 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. Oil & Gas: couplings for onshore production systems e.g. sucker rods. 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. Mining: bushings and bearings. 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. | |
