Zinc-plated spring steel wire and piano wire 'MAC WIRE'

Zinc-plated spring steel wire and piano wire 'MAC WIRE'

VA proposal materials that enable significant cost reduction without the need for post-plating!

Our company offers the zinc-coated spring steel wire and piano wire "MAC WIRE," which combines excellent corrosion resistance and coiling properties. "MAC WIRE" has a lower risk of rust starting from the cut surface of the steel wire, and there is also minimal concern about hydrogen embrittlement due to plating treatment, which is more of a concern with high-strength materials. 【Features】 ■ Pure zinc-coated steel wire through electroplating, offering excellent corrosion resistance against base steel ■ Several times better coiling properties compared to conventional zinc-coated materials for springs ■ A VA proposal material that significantly reduces costs as no post-plating is required ■ Lower risk of rust starting from the cut surface of the steel wire ■ Minimal concern about hydrogen embrittlement due to plating treatment, especially with high-strength materials *For more details, please download the PDF or feel free to contact us.

Copper-plated piano wire for conductive springs "Mac Wire CP"

Copper-plated piano wire for conductive springs "Mac Wire CP"

Spring forming processing, low-temperature heat treatment possible! Piano wire for springs with copper plating using an electroplating method.

"Macguire CP" is a high-strength copper-plated piano wire developed primarily as a spring material requiring conductivity, featuring excellent corrosion resistance, superior coiling properties, and spring characteristics. Since copper plating is unnecessary after spring forming, it eliminates concerns associated with post-plating, such as spring entanglement, spark marks, hydrogen embrittlement, uneven plating around the coating, and poor plating in spring contact areas. 【Features】 ■ Equivalent level to spring phosphor bronze wire ■ No deterioration in conductivity even if the copper-plated surface discolors due to oxidation ■ Possesses very excellent coiling properties unique to copper plating and also excels in soldering performance ■ Even if the copper-plated surface discolors due to oxidation, the corrosion resistance against the base steel can sufficiently withstand 96 hours in a salt spray test, demonstrating high corrosion resistance. *For more details, please refer to the PDF document or feel free to contact us.

Piano wire "compression coil spring"

Piano wire "compression coil spring"

Introduction of piano wire compression coil springs that bear loads at the center of the coil.

The "compression coil spring" is referred to as a "compression spring" and is a spring that receives load at the center of the coil. The end face shapes include open ends with uncoiled ends and closed ends with a seat coil that makes the end face flat. Generally, the end faces are ground to make them flat to prevent load bias and damage to mating parts. For springs with a small wire diameter (thin wire), grinding may be omitted as they have less impact on load bias and the mating parts. 【Features】 ■ Piano wire ■ A spring that receives load at the center of the coil ■ Available in open ends and closed ends ■ Prevents load bias and damage to mating parts *For more details, please refer to the PDF document or feel free to contact us.

Piano wire "twisted coil spring"

Piano wire "twisted coil spring"

Introduction to Piano Wire Twisted Coil Springs

The "twisted coil spring" is a spring that receives a torsional moment around the coil's central axis. There are cases where it is used by winding it in and cases where it is used by unwinding it, but generally, it is used in the winding direction. When subjected to a load, the coil diameter changes significantly. It is necessary to allow some space with the mounting components. 【Features】 ■ Piano wire ■ A spring that receives a torsional moment around the coil's central axis ■ Generally used in the winding direction ■ The coil diameter changes significantly when subjected to a load ■ It is necessary to allow some space with the mounting components *For more details, please refer to the PDF document or feel free to contact us.
