Tin is a silver-colored, ductile metal whose major purpose is to promote solderability to otherwise unsolderable base metals.
Tin-plating process is applied extensively to protect both ferrous and non-ferrous substrates. Tin being non-toxic, ductile and corrosion resistant is frequently used for the food processing industry. The excellent ductility of tin allows a tin-coated base metal sheet to be formed into a variety of shapes without damage to the surface tin layer. It provides sacrificial protection for copper, nickel and other non-ferrous metals, but not for steel.
Tin protects the base metal from oxidation and preserves its solderability, properties ideal for the electronics industry.
Nickel is mainly used on MS for corrosion protection and for its attractive appearance, parts processed with Bright Nickel plating maintain their surface appearance and brightness over a period of time. Best used as an undercoat for silver, gold and brass finish, Nickel plating is done on Zinc and Zinc die casts, Copper and CopperAlloys, Aluminium and Aluminium die castings with an undercoat of Copper.
Nickel is extremely resistant to atmospheric corrosion, making it an excellent choice as a final layer.
Nickel is also a magnetic material, making it an attractive option when magnetic properties are required.
Nickel can provide improved wear resistance to soft metals such as copper, resulting in longer service life.
Nickel also provides a superior barrier layer between metals that can experience self diffusion into each other such as copper and tin.
We do 99.9% pure Silver plating on various metals. Silver plating is mainly carried out for two reasons. One is to enhance electrical contact and the other is for decorative components like switchgears and panel boards.
Silver plating is being used since the 18th century for cheaper decorative household items, cutlery and silver plated tableware. It is used on a wide range of statues, idols artefacts and decorative items.
The AL ASHRAFI Group of Companies was founded in 1989 and since then we have pursued an unstinted path of growth despite national and international competition. Growth with a social conscience has been our motto. Our long-term goal of building a global, multi-product, multi-brand company is now becoming a reality.0 comments
We are doing 24 kt Swiss Gold electroplating on various metal surfaces. Gold electroplating has excellent electrical and thermal conductivity, Offers exceptional solder ability and is a superb reflector of infrared radiation. In addition gold is a noble metal which does not oxidize or chemically react under normal circumstances. Gold plating is planned for electrical applications and where great consumption resistance or high stain resistance is required.
Gold plating is popular on various Medals and Momentoes, trophies , idols and artefacts.Besides, Gold plated indoor signage adds to the image of the user.
