Use titanium alloy material instead of wood piano accessories

Titanium is a new type of metal, the performance of titanium and the content of carbon, hydrogen and oxygen content, the density of titanium alloy is generally about 4.51 g / cm3, only 60% of steel, its specific strength is higher than most metal structure materials, can produce high unit strength, good rigidity and light quality parts. It has the basic characteristics such as light quality, high strength, corrosion resistance, high temperature resistance and low temperature resistance. It plays an extremely important position in the engineering materials used in weapons and equipment, aerospace and national defense industry and has been applied in practical applications.

Titanium alloy material characteristics of the replacement of wood accessories have advantages. The thermal conductivity of titanium is 1 / 4 of steel, 1 / 13 of aluminum, 1 / 25 of copper, the thermal conductivity of various titanium alloys is about 50% lower than titanium metal, the thermal conductivity of titanium alloy TC4 at 200℃ l=16.8 W / m ℃, relative to the wooden structure, more rigid, not easy to deformation, not affected by the temperature change caused by stage air conditioning, stage equipment and lighting equipment. Titanium alloy is better in corrosion resistance than wood in humid environment, and titanium alloy can still maintain its characteristics at low temperature and ultra-low temperature. Therefore, the use of titanium alloy to replace the wooden piano accessories, can avoid the faults caused by environmental impact, improve the piano use efficiency, prolong the life, and save time and economic costs.

After titanium alloy replaces wood accessories, the coating process can be used to avoid the impact of sound caused by the quality change of accessories. Titanium produces strong chemical reactions with substances such as O2, N2, H2 and CO2 in the atmosphere, forming a corrosion-resistant hardening layer. The mechanical and corrosion resistance of titanium alloy can be further enhanced. In addition, the chemical affinity of titanium is good, easy to produce adhesion phenomenon with the friction surface, to adapt to the uneven surface characteristics of wood accessories. After replacing wooden keyboard accessories or coating, wood accessories can ensure that dry crack, mildew and deformation are not affected by external forces, and maintain the original state of wood accessories. Accessories can also be protected by coating method to reduce the impact of quality changes of accessories.

Secondly, most of the wood accessories need a long production cycle, the production process of drying, drying and fumigation process, the environment and process requirements are high, a lot of energy, site and time consumption. After using the titanium alloy material or coating, the wood accessories can be directly added to the coating, to achieve the purpose of maintaining the form of the accessories for a long time, shorten the piano making time, and improve the strength of the accessories.
