Overview

Custom-made for batteries

Tata Steel Plating is the world's leading supplier of materials for the production of battery cases. HILUMIN, the nickel-coated steel strip is specifically developed for battery applications. It is created by electroplating cold-rolled battery quality steel with nickel and diffusion annealing. HILUMIN offers low contact resistance and high corrosion resistance. It is used in alkaline battery cans (including AA, AAA, C, D and 9V) and all other battery types including rechargeable and ZincAir.

HILUMIN Cobalt has an additional thin Cobalt layer on top of the nickel coating for extended shelf life.

HILUMIN offers the coating and mechanical properties that you require for high speed can making and contribute to cell reliability so our customers can guarantee up to ten years of shelf life .

Benefits

Superior performance

HILUMIN is produced from ultra-clean, specially-cast steel. Our proven and dedicated plating and heat treatment process ensures high corrosion resistance for long battery life. The consistent quality of HILUMIN also meets the demands of high volume, high speed battery component production. HILUMIN is custom-made for each application and is available for any battery type (alkaline, lithium, NiMH, NiCd and Li-Ion, Zn Air). It is also available as perforated steel strip. HILUMIN comes in a wide variety of finishes and offers:

outstanding formability (with excellent adhesion) for high-speed can-making and cell assembly
excellent corrosion resistance and low contact resistance
excellent deep drawing capability
consistent mechanical properties and tight tolerances
low earing characteristics

Extended shelf life

For an even more advanced coating performance, HILUMIN Cobalt offers additional cobalt plating as a top coating. This HILUMIN cobalt strip outperforms the traditional alkaline battery can - enhancing cell performance considerably after ageing. If you are concerned about edge corrosion, we can also provide our HILUMIN coating on top of stainless steel.

Main benefits of HILUMIN include:

end-products of consistent and reliable quality
opportunities to enhance end-product performance
trouble-free, repeatable processing
scope to optimise processes
minimised yield loss
