Gold plating
It has excellent electrical conductivity, corrosion resistance, and wear resistance. Additionally, due to its excellent light reflectivity, it is widely used as a decorative surface treatment. Neodymium magnets are often coated with nickel plating on the base. Note that gold plating is different from gold-colored plating.
High-performance Sn-Cu alloy plating and tin plating developed in-house.
This is a barrel gloss Sn-Cu plating developed in-house. It has very good soldering characteristics and discoloration resistance. It is currently being mass-produced using automatic machines and is being used in the mass production of several customers. As of May 2003, it has achieved a record of over 30 million pins per month.
![Surface treatment technology: No cyanide, no nickel alloy plating [No toxic substance management required]](https://image.mono.ipros.com/public/product/image/e26/2000110230/IPROS964251046483181981.jpg?w=280&h=280)
A surface treatment technology that requires no toxic substance management! Free booklet on alloy plating technology!
Shimizu's surface treatment technology, the "No-Cyan No-Nickel Alloy Plating" series, is a new surface treatment technology that eliminates the toxic substances cyanide and nickel. The use of cyanide and nickel has raised numerous issues regarding the safety of workers' working environments and the designation of carcinogenic substances. The "No-Cyan No-Nickel Alloy Plating" series addresses these problems. It is widely adopted in the manufacturing industry and has a proven track record in decorative applications such as building materials and amusement, as well as in the medical industry. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ★ We are currently offering a free technical booklet that explains alloy plating ★ If you are interested, please download the catalog or contact us. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ [Contents] ■ Why No-Cyan? ■ Why No-Nickel? ■ Overview of the No-Cyan Alloy Plating Series ■ How is it managed? *For more details, please download the catalog or contact us.
It is a neutral tin-copper alloy plating that does not contain cyanide compounds.
Traditionally, the plating for nickel allergy has primarily been copper-tin alloy plating using cyanide. This copper-tin binary alloy plating is a neutral nickel alternative plating solution that does not use any harmful substances such as cyanide compounds or fluorides. It is a non-magnetic plating with a shiny white appearance. For more details, please contact us.

RoHS compliant, JIS certified molten zinc-aluminum alloy coating
The molten zinc-aluminum alloy coating "GALVA LEO" is a high corrosion-resistant coating that contains 5% aluminum and 1% magnesium based on molten zinc. It demonstrates excellent corrosion resistance in a wide range of fields, including salt damage, heavy industrial areas, civil engineering, construction, electricity, telecommunications, and railways. 【Features】 ■ Compliant with RoHS, JIS certified (JIS H 8643) ■ Proven performance of over 10,000 hours in salt spray tests (in accordance with JIS Z 2371) ■ Compatible with bolts, nuts, and washers ■ High adhesion, with adhesion to iron equivalent to that of molten zinc coatings *For more details, please refer to the PDF document or feel free to contact us.
Usable from thin sizes! RoHS compliant product with corrosion resistance equivalent to hot-dip galvanizing.
KSG plating is a zinc-tin alloy plating. We have been developing it independently for over 20 years, repeatedly improving it to complete the current method. While there are alloy platings that include tin in the field of electroplating, the molten tin alloy is a technology handled only by Kowa Industrial. Additionally, by adopting a centrifugal method, it prevents accumulation and enables the reduction of subsequent processes, achieving high quality at low cost. 【Features】 - Corrosion resistance is almost equivalent to that of molten zinc plating and is relatively strong in acidic environments. - Salt damage resistance is superior to that of molten zinc plating. For more details, please contact us or download the catalog.
In the salt spray test, it has ten times the corrosion resistance of conventional hot-dip galvanized coatings.
SG plating is a molten zinc alloy plating system consisting of 5% aluminum and 1% magnesium. It is an alloy based on zinc, developed with technical support from Mitsui Mining & Smelting under the name "Super Galva," and has incorporated unique technologies from Kowa Industrial for over 20 years. While zinc-based alloys with approximately 5% aluminum have been commercialized in the steel sheet sector by blast furnace manufacturers, with JIS standards established, such plating is often technically challenging in the general molten zinc plating field, and this type of plating is rarely performed. Furthermore, there are no other facilities boasting a production capacity of 3,000 tons/month with an 8-meter large kettle for alloy plating. SG plating has a proven track record in harsh environments prone to corrosion from salt damage, such as coastal areas and heavy snowfall regions. Recently, in collaboration with Nippon Steel, we have successfully developed high corrosion-resistant steel pipes. By combining Nippon Steel's "Strong Seam," which has a proven track record as a well-processable steel pipe, with SG plating, we have achieved steel pipes that excel in corrosion resistance and processability. 【Features】 - Exceptional corrosion resistance - Excellent as a base for painting - Powerful enough to handle large-scale production - Environmentally friendly surface treatment For more details, please contact us or download the catalog.
Achieves 2 to 3 times the corrosion resistance of trivalent black! Significantly improves the shortcomings of trivalent black, such as "poor color tone" and "weak against scratches"!
Commonly known as "High Nickel Black," this surface treatment is achieved by applying a chemical conversion treatment to an alloy plating of 15% nickel and 85% zinc, resulting in corrosion resistance that is 2 to 3 times greater than trivalent black. This surface treatment significantly improves the shortcomings of trivalent black, such as "poor color tone" and "vulnerability to scratches."
