“The future isn’t wire – less”

Fine Wire Products and Precious Metal Plating Technologies

Our business idea: With a flexible and service-orientated organization develop, produce and provide global markets with high-quality precision wire with focus on long term business relationships characterized by high technology and niche needs. In Luma´s ”micro(n)world” everything starts with the customer. Creating long-lasting ”sustainable” customer relationships lies in the nature of our business because it often takes a long time to create products according to our customers demands. Thus we want to be the natural choice partner No1  for our customers in development of innovative solutions within the Fine and Ultra Fine Wire (UFW) sector.

Luma Metall AB is an independent producer with its head
office and production plant in Kalmar, Sweden.
