Filter/Mesh’s Materials

Stainless steel (ring/mesh)

Stainless steel is a rust-resistant material that is easy to process. Its main component is iron, but an oxide film is formed on its surface, making it rust-resistant. There are more than 100 types of stainless steels in the JIS standard for steel materials alone, and we would like to introduce some of the main types of stainless steels we handle.

Type Description
SUS304 SUS304 is a stainless steel containing 18% Cr and 8% Ni, and is the most widely distributed of the stainless steels.
SUS316 SUS316 is a stainless steel containing 18% Cr and 12% Ni, to which molybdenum (Mo) is added to further improve corrosion and pitting resistance compared to SUS304.
SUS304L Lower carbon content than SUS304, superior corrosion resistance, more expensive material than SUS304.
SUS316L Lower carbon content than SUS316, superior corrosion and pitting corrosion resistance, and more expensive than SUS316
SUS430 Superior in both corrosion resistance and strength, but inferior to SUS304. Less expensive than SUS304. Often used for products around water.

Although stainless steel has superior corrosion resistance compared to regular steel, their may be concerns of rust forming depending on the operating environment. For such customers, we propose SUS403 and SUS316L, which have lower carbon content and higher corrosion resistance. Alternatively, bright annealing treatment is available.

Brass (Ring/Mesh)

Brass (brass) is an alloy of copper and zinc, with at least 20% zinc. A typical example is the 5 yen coin. It has excellent ductility, can be easily processed into complex shapes, and is easy to cut.

SuperDyma (ring)

SuperDyma is a highly corrosion-resistant plated steel sheet and is a registered trademark of Nippon Steel & Sumitomo Metal Corporation. It contains approximately 11% aluminum, 3% magnesium, and a trace amount of silicon. It has high corrosion resistance and performs well in strong alkali environments. Also, as no post-plating is required, it results in cost reduction.

Titanium nonwoven fabric (prototype)

In the past, we have successfully rounded and welded sintered titanium non-woven fabrics for prototypes. Since sintered titanium nonwovens are not flexible, it is said that it is difficult to round and weld them cleanly. Characteristics of Titanium are as follows:


Although not as light as aluminum, titanium is 2/3 the weight of iron and 1/2 the weight of copper.


Titanium is very strong against heat, and its crystals change their structure to become more heat-resistant when temperatures exceed 885℃.

Excellent corrosion resistance

Titanium has very high corrosion resistance, and resistance to seawater. It is also is resistant to acid and does not melt easily.

What is bright annealing?

Bright annealing is a treatment method that reduces oxides by heating and cooling in a reduced atmosphere. The weld burns that occur when welding metals and other materials can lead to the possibility of rusting. Bright annealing removes oxides to maintain durability, protect machine performance, and prevent deterioration of service life. Also, by removing the black discoloration, the finish becomes cleaner. We can handle a range of diameters from φ4 to φ80.
