Description

Hardiall® is a wrought spinodally hardened copper alloy CuNi15Sn8 (C72900) designed for high strength applications where toughness is required. It is non-magnetic and resists mechanical wear, galling, stress relaxation, corrosion and erosion. It is easily machined into complex components whilst being environmentally friendly being both lead and beryllium free.


Hardiall® is used within the aerospace, oil & gas and other industries thanks to its outstanding physical and mechanical properties in many varied components. Lebronze alloys has developed a full range of Hardiall® products to match it’s customers’ stringent needs. Lebronze Alloys manufacturing process for Hardiall® is fully integrated: internal processes include casting, hot and cold working stage, heat treatment and non-destructive testing. Being fully integrated ensures reactivity and complete traceability.

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.
