钢琴的钢丝主要材料是低碳素钢，其延展性很强，并且在锤子强力反复敲击后不会变形。一般为了获得好音色，大多数是不加涂层的。为了防锈加了涂层的钢丝在音色上不如不加涂层的柔和。The main material of the piano’s steel wire is low-carbon steel, which has strong ductility and will not deform after repeated tapping of the hammer. Generally, in order to get a good tone, most of them are not coated. In order to prevent rust, the coated steel wire is not as soft as the uncoated.

目前除了美国的施坦威钢琴有专利以外还有两个厂家生产琴钢丝——德国ROSLAU弦和日本SUZUKI弦，其中ROSLAU用量占了90％以上。世界上许多著名品牌钢琴一般都是用的这两个品牌的琴钢丝。At present, in addition to the patents of Steinway pianos in the United States, there are two manufacturers that produce steel wires – German ROSLAU strings and Japanese SUZUKI strings, of which ROSLAU accounts for more than 90%. Many famous brands of pianos in the world generally use these two brands of piano wire.

琴弦生锈了会降低它的抗拉强度和抗弯强度，容易在弹奏的时候断弦并且音色变差。特别是弦轴生锈了会使弦轴孔对弦轴的握着力减退，这其中也就导致了“走音”。Rusting of the strings will reduce its tensile strength and bending strength, and it is easy to break the strings and deteriorate when playing. In particular, the rust of the string shaft will reduce the grip of the string shaft hole on the string shaft, which also leads to “sound loss”.

钢琴为什么会生锈，其中金属生锈所需要的两个必要条件——氧气和水（一般指空气里的水分）。金属接触的空气中水分越高，生锈的速度就越快，钢琴木材和金属的构造本身对干湿度就很敏感。气候条件影响的环境湿度，影响了钢琴内部环境湿度。若钢琴的制造工艺存在严重问题比较少见，一般对于品牌钢琴来说一旦出现，无法彻底改善。Why does the piano rust? There are two necessary conditions for metal rust – oxygen and water (generally refers to the moisture in the air). The higher the moisture in the air that the metal touches, the faster it rusts. The structure of piano wood and metal itself is very sensitive to dry humidity. The ambient humidity affected by climatic conditions affects the environmental humidity inside the piano. If there are serious problems in the manufacturing process of the piano, it is relatively rare. Generally, once the brand piano appears, it cannot be completely improved.

最好的保护方法就是控制好室内的温度湿度，定时的钢琴调音。已经生锈的琴弦，由专业钢琴调律师用钢琴专用丝棉（3M）进行擦拭，配置专业的润滑保养辅助用品等给予处理解决为宜。经过处理后的音色焕然一新，音色的改变具有非常明显的变化。The best way to protect is to control the temperature and humidity in the room and tune the piano regularly. The rusty strings are wiped by professional piano tuning lawyers with special piano silk cotton (3M), and it is appropriate to be equipped with professional lubrication and maintenance accessories. After processing, the tone has been refreshed, and the change of timbre has a very obvious change.
