High strength steel
Corrosion protection of steel is an important feature to maintain functionality in demanding applications. Our Anti-corrosion coatings provide a uniform black/silver appearance, modify friction / conductivity characteristics as well as improving abrasion resistance and paint adhesion.
The polymers that are being used for decorative trim, electronic components, displays and in-mold electronics are modified to provide; style, individuality, functionality, value, and reliability in various automotive applications. Our surface coatings are applied to plastics to improve aesthetics, haptic feel, and durability.
Aluminum is used in Chassis, battery packs, thermal management systems, powertrain, interior and exterior parts. For many automotive applications the performance needs to be further enhanced using various surface technologies.
We understand protecting and enhancing aluminum, plastic and high strength steels.
For over 50 years we have been developing technology which treats these materials. Today, our compliant products exceed most automotive requirements:
- Protecting aluminum in vehicles from corrosion
- Plating plastic chromium vehicle trim
- Protecting steel fasteners from substrate and contact corrosion
For a company which supplies products and expertise worldwide for all these needs. ESI Automotive. Already on it.
Lightweight materials for vehicle weight reduction
To enable car weight reduction, new alloys and castings have been developed. This allows designers to make further use of aluminum in cars.
According to European-aluminum, The amount of aluminum in cars is around 150 kg. This could rise to 196 kg by 2025. The significance of this? 100 kg of aluminum in vehicles reduces CO2 emissions by up to 8g per kilometre travelled.
Automotive engineers and material suppliers are investing in research and development of lightweight, high strength, readily formable materials. For example, high strength steel suppliers are developing generation three (gen-3) steels which have very high tensile strength as well as high elongation; hence, they can be cold formed.

About surface coatings used in reducing vehicle weight
Aluminum in vehicles needs protecting. It also needs coatings which improve paint adhesion. These coatings must provide both corrosion resistance and meet organic coating adhesion tests. They must also be free of hexavalent chromium.
Describes the electroplating of decorative metals onto ABS* based plastic.
First the ABS need is metalized. This achieved by etching the surface. Then coating the roughened surface with traces of a precious metal. This process provides 'seeds' for depositing the copper, nickel and chromium layers.
High strength steel needs coatings to provide corrosion resistance. On threaded fasteners they should meet predefined coefficient of friction ranges. Being high strength, coatings should also prevent the risk of hydrogen embrittlement.
For example, ZinKlad 1000 coatings have a high a surface hardness of 500 HVN. This makes them ideal for self-thread cutting threads, as they will not be removed on assembly.

High strength steel
Steel is still the most common material used in cars. It’s strong, cheap, and easy to work with. There are many different grades of high strength steel, offering significant weight reductions. The use of innovative new grades of steel will rise.
Plastics are used in many different applications and make about 50% of the vehicle’s volume but only 10% of its weight. There are many different plastics being used, the performance is defined by material design, process parameters and processing technologies.
