Sachs material selection saxophone material selection is divided into three types: brass, phosphorus copper, nickel alloy and so on. Brass, which is the most commonly used material, its personality is not bright, it is this characteristic that gives him a variety of distinctive personality. Metal, Bakelite, etc. The mouth of a variety of materials gives the brass saxophone the difference, which is made of copper and zinc alloy. Features are cheap and easy to process, such as plate gold and pull holes. The tone is gentle. Now the market is widely sold is this material! Phosphorus copper, phosphorous copper material is relatively brittle, this kind of copper material is very hard, the tone color will be suffocated, can not resonate, is not easy to process, so domestic phosphorous copper has only appeared in front of people in recent years with the innovation of technology. The material of the phosphate copper tube gives it a strong personality. Its voice is very bright and has a very strong personality. Put the pipes of various materials together and blow, the sound of the phosphorus copper pipe is the most prominent. Nickel alloy: this material is the brightest timbre at present, the performance of jazz style is very outstanding, that is, the high voice is easy to have metal murmur, the mouth should be used more timbre, the whistle needs a little selection, This material is very good for jazz style. Nickel as the main addition of copper-based alloy, silver-white, metallic luster. Compared with other copper alloys, the mechanical and physical properties are very good, good ductility, high hardness, beautiful color, corrosion resistance, rich deep impact properties, the relative price will be more expensive, also known as copper.
