High production cost: Compared with brass, the material cost of red copper is higher, and the technical requirements for processing red copper are higher, so the cost is higher and the price is more expensive.
2. High rarity: the application range of red copper is wider, but the output is relatively small, so the supply of red copper products has been in short supply, so the price is higher.
3. Unique color: copper has a unique color and looks more textured, so its value is higher.
