れている。(Prior art) Die casting methods such as Zn die casting method, Al die casting method, Mg die casting method, etc. are methods in which Zn or Zn alloy, A1 alloy, Mg alloy, etc. are cast under pressure, and products with complex shapes are cast. It is widely used because it is good for the skin. In addition, a method of enclosing objects of other shapes during casting is carried out in boat fishing. For example, Japanese Patent Application Publication No. 55
No. 69356 discloses a method for producing a pulley, which comprises placing a preformed grooved ring in a mold, and casting the ring by casting while correcting the groove shape using casting pressure.

がら、Ｚｎ合金は比重が７前後と重く、しかも高価であ
り、軽量化、低コスト化を達成する上で不利である。(Problems to be Solved by the Invention) Zn or Zn is used as a molten metal material in a die-casting method.
Alloys are excellent in that they have a low melting point, good fluidity, can be cast into complex-shaped parts with good skin, and have a long mold life, and are used for a variety of parts. Zn alloys also have excellent vibration damping ability, and are particularly suitable for use in areas that are susceptible to vibrations, such as thin-walled parts, and areas that are likely to generate noise due to vibrations, such as the cylinder head of an air-cooled automobile engine. It is valid. However, Zn alloy is heavy with a specific gravity of around 7 and is also expensive, which is disadvantageous in achieving weight reduction and cost reduction.

ＺｎまたはＺｎ合金を使用せざるを得なかった。On the other hand, A1 alloy and Mg alloy have low specific gravity and can achieve weight reduction, but have a higher melting point and poor fluidity than Zn alloy, making it difficult to form complex shapes. Furthermore, it is inferior to Zn alloy in terms of mold life and damping ability. For this reason, when casting parts with complex shapes, At alloys are not suitable, and Zn or Zn alloys, which have a high specific gravity and are expensive, have to be used.

問題があるため、実用化に至っていない。In order to solve the above problem, it is conceivable to form only the complex-shaped part with Zn or Zn alloy, and the other parts with A1 alloy or Mg alloy, but in order to obtain such a product, , simply Znn all remaining parts AI or Mg
Merely joining alloy members together has not been put to practical use because there is a problem with the strength of the boundary portion.

The purpose is to cast a product with excellent damping ability and light weight.
