Luma Tungsten wire is the best alternative for production of high end musical strings. With characteristics such as constant values in diameter, ovality, tensile strength and elongation – prominent producers of exclusive musical strings choose LUMA Metall as their raw material supplier.
Tungsten wire has proven to be the best alternative for exclusive strings, in competition with various alternatives using various materials. The usage of Tungsten wire for musical strings has been, and is still increasing. Due to its exclusivity, Luma Tungsten wire is used for instruments such as cello and viola.
High end musical strings
High end musical strings are made of Tungsten wires for one main reason – the high density of Tungsten. Tungsten has for example twice as high density than that of steel. The high density makes it possible to produce thinner musical strings without losing frequency.
A thinner string makes it easier to play, and the extra density of the Tungsten wire gives the string more projection, good weight and tension and makes it louder with a quick response. “Winding with Tungsten provides a deep, warm, focused sound with great power and personality.”
Tested musical strings
Luma Tungsten wire for musical strings is fully tested for constant diameter, ovality, tensile strength and elongation. It is crucial that the wire has a high elongation and is not brittle. Brittleness will make the coiling of the wires impossible. Uniform values in dimension and low ovality is vital to obtain a high quality musical string.
The electrical conductivity is good, about 30% of copper, as well as the thermal conductivity, which is about 43% that of copper. Tungsten has the lowest coefficient of thermal expansion, and at temperatures above 1650 °C the highest tensile strength of all metals. Tungsten has unusually low specific heat, which combined with the good thermal conductivity means that the metal heats up and cools down very quickly. That is a benefit with a fine tungsten wire.
