Alloys and Applications

Providing cutting edge and specialty alloys for a wide range of industries and applications. Our flexible manufacturing capacity, low minimums, and short lead times have made us an industry leader.

LN Industries has been delivering quality, precision materials and services for over 100 years. Initially we established ourselves as a supplier to the exacting needs of the watch and jewelry industries, providing small diameter tubing in standard and custom profiles. We have since grown into a major world supplier of precision tubing. We provide many hard to find grades of metal and non-ferrous materials as well as stainless steel, high temperature alloys, and aluminum. With the capacity to manufacture in coil form as well as straight lengths, to small precision cut pieces with varying precise tolerances.

The key to our success is flexibility and customer service; we provide fast order turn around, with very low minimums, and quick quotations provided by knowledgeable professionals.
