If you have a question about a topic that is not covered here, please don't hesitate to contact us.
- What are the pros of molten solder?
-
Solder is diffusion boded and isn’t peeled of, which means that it is appropriate for strong bending.
It is possible to make stripe pattern without masking and rare to cause whisker formation.
Also, solder powder doesn’t spread a lot in pressing, so there are cases in which you don’t need to use a dust collector.
- What kind of industries are your materials used in?
-
Our materials are used in various industries comparatively equally.
For example, they are used for electric devices, automotive parts, precision equipment, textile machines, cutter and various equipment.
- Does molten solder contain lead?
-
Of course, it’s lead-free. (RoHs compliant)
- What are the pros of clad metals?
-
It is possible to utilize the characteristics of different types of metals.
Also, it is possible to produce a thick metal which plating cannot produce and
one-side, both-sides and edge lay cladding can be produced by changing manufacturing patterns.
For further information, please check clad page.
- Can you manufacture sheets?
-
Yes we can.
Length tolerance example:
◆Length of less than 2,000 mm: Tolerance +5mm / -0mm
◆Length of 2,000 mm and over: Tolerance +10mm / -0mm
