Strong combination

altrix® multilayer roll-bonded clad plates manufactured by means of the in-house-developed cladding-by-rolling method as two-ply or three-ply plates. The base material features high degrees of toughness and good weldability. The coating material features highest strength and wear resistance in hardened condition.

Areas of application

Multi-layer altrix® plates are typically used in applications such as suction dredger tubes, ridge forming plates, wear plates on roll housings and in mold engineering, paddles in log washers, slides, chutes and transfer plates in the sand, gravel and concrete industry.

Materials

The standard base material of altrix® multilayer plates is steel grade S235 pursuant to EN 10025-2. The coating material used is 2842 (altrix 90). In hardened condition, a hardness of up to 66 HRC can be achieved. altrix® plates are delivered in as-rolled condition.

Dimensions

• Sheet thickness: 7–80 mm 
• Maximum sheet width 3,800 mm 
• Maximum plate length 12,000 mm 
• Ordered weight: at least 10 tons per line item 
• Maximum unit weight 6.3 tons per single plate 

The correct coating thickness distribution must be determined while taking into account the desired wear resistance and resistance to failure. A thickness ratio of 50/50 between the cladding and the base material is typical for two-layer plates, and a ratio of 33/34/33 (hard/tough/hard) for three-layer plates.

Advantages of altrix® 

• Longer service life due to 
• high hardness and resistance to failure of the coated metal 
•  Smooth surface: good flow behavior, little zinc build-up 
•  Best weldability in as-delivered and hardened condition 
•  Simple fastening procedures
