All of these industries demand reliability, exceptional levels of service as well as Quality products, technical knowledge and supply chain management and integration at all levels.

Righton & Blackburns, as a Preferred Distributor for LBA in the UK and Ireland for High Integrity Copper Alloys and the exclusive distributor for Hardiall®, can deliver all of those industry requirements. Working in partnership with LBA we provide a seamless supply chain from manufacturer to end user, working as a single team.

High Strength Spinodal Copper Nickel Tin Alloys

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 and is environmentally friendly being both lead and beryllium free.

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.

Oil & Gas

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.

Applications
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 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 downtime.

For these applications Lebronze alloys’ integrated supply chain can propose ready-to-use products.

Aerospace

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 are required to operate under severe conditions; they need to be lubricated and replaced frequently causing 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 coppernickel- aluminium based alloys or where lubricity is critical and titanium cannot satisfy the engineer’s requirements.

Other applications include: Landing gear attachments, engine and pylon attachments, flight control mechanisms, doors and hatches.

Mining

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 matching the stringent needs of the mining industry.

Applications
Bushings and 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.
