Pianodraad

Pianodraad, also known as piano wire, is a high-carbon steel wire used primarily for the strings of pianos and other stringed instruments. It is known for its high tensile strength and elasticity, which are crucial for producing clear and sustained musical tones. The manufacturing process involves drawing steel rods through a series of progressively smaller dies to achieve the desired diameter and strength. The specific alloy composition and heat treatment are carefully controlled to optimize its acoustic properties.

The tension of pianodraad strings is a significant factor in the piano's sound and tuning stability. Thicker and longer strings are used for lower notes, while thinner and shorter strings are used for higher notes. This variation in string properties, combined with the striking action of the hammer, creates the piano's wide tonal range. The quality of the pianodraad directly impacts the instrument's resonance, sustain, and overall sound richness. Beyond pianos, similar high-tensile steel wires are also found in harps, clavichords, and some types of guitars. Its exceptional strength-to-weight ratio also lends itself to other applications where durability and resilience are paramount, such as in certain types of springs and cables.
