Metals

Suitable base materials for chrome plating are non-ferrous and ferrous metals, stainless steel and die-cast zinc.

Chromium coatings are popular in the automotive, furniture and many other industrial sectors for their decorative appearance. Fields of application of hard chrome are heavily stressed workpieces such as brake discs, ball valves in pipelines or rollers and cylinders of all kinds in the printing industry, film production, paper production, the food industry and in mechanical engineering.

The copper plating is suited for non-ferrous and ferrous metals, stainless steel and die-cast zinc.

Copper coatings alone are seldom needed, as copper tends to turn green, especially in moist air. However, it can serve as a painting substrate or as pre-treatment before other surface treatments. Components coated in this way are used for decorative purposes or in the electrical and electronics industries (e.g. connectors).

The range of materials which can be finished using DURALLOY^® includes steels up to 62 HRc and up to 15% chromium content, stainless steels, grey cast iron, sintered metals and bronze.

DURALLOY^® coatings protect against pressure loads, inadequate lubrication, friction corrosion and vibration corrosion. They withstand high temperatures as well as corrosion and wear. They ensure low friction and dry lubrication. DURALLOY^® coatings are particularly suitable for linear guides or ball bearings and are also suitable for components that are exposed to aggressive gases (rolling mills, metallurgy, defence technology).

The most important client sectors are: automotive, decorative areas, printing press manufacture, hydraulics, industrial gears, aerospace, medical technology, offshore sector, textile machines, rolling bearing technology, defence technology and machine tools.

Gold and gold cobalt are deposited on aluminium alloys, non-ferrous and ferrous metals and titanium materials. Only gold plated are additionally stainless steel and die-cast zinc.

Gold and gold / cobalt alloy coatings are for example suitable for connectors for the electronics industry, batteries, LED manufacturing, professional halogen lamps, aerospace components, radar equipment, and high temperature brazing.

Non-ferrous and ferrous metals, stainless steel and die-cast zinc are nickel-plated by us.

Nickel-plating as a final coating for components is a possible alternative to chrome coatings in the decorative sector. As a final coating, nickel can be polished very well from matt to glossy. Nickel layers are in demand, above all in the automotive industry and in electrical engineering / electronics.

A nickel sulfamate treatment is suited for aluminium alloys, non-ferrous and ferrous metals and stainless steel.

Nickel sulphamate is especially recommended when extremely thick, stress-free coatings are needed. Such nickel coatings also serve as a primer for thermal spray coatings.

We silver-plate aluminium alloys, non-ferrous and ferrous metals, stainless steel, titanium materials and zinc die-casting.

Due to their outstanding electrical conductivity, silver coatings are frequently used in the electronics, high-voltage and telecommunications industries, amongst others: electrical switches, high-voltage conductors or housings. In addition, silver is often used in the food industry and the chemical industry. For example, stainless steel fittings and shut-off valves are silver plated to prevent seizing and corrosion.

At Aalberts surface treatment we tin-plate aluminium alloys, non-ferrous and ferrous metals, stainless steel, titanium materials and zinc die-casting.

Tinning is mainly for technical parts that must be electrically conductive, solderable and electromagnetically shielded: housings for electrical plugs, plug contacts. Self-lubricating bearings are also an application for both tin and silver coatings.

Galvanising is usually carried out on steel alloys.

Galvanic zinc is used in all conceivable sectors, such as the automotive industry, sanitary technology, construction and fittings industries as well as the metalworking industry, in areas with normal temperature loads right through to high corrosion protection requirements.

Base materials are steel alloys and ferrous materials, including cast iron.

Typical application opportunities can be found in the automotive industry, construction machinery industry, sheet metal processing, electrical engineering as well as instrumental and mechanical engineering.

Base materials are steel alloys and ferrous materials, including cast iron.

Classical applications of components with zinc-nickel coatings are engine compartments, chassis and underbody areas in automotive engineering, as well as the offshore sector.
