Here are some points to choose the right material for the bicycle dental tray:

Strength and durability:

1. High-strength materials can withstand the pressure and impact during riding, such as high-quality steel or some high-strength aluminum alloy.

2. Ensure that the material has good durability and can maintain stable performance in long-term use.

Lightweight:

1. Consider lighter materials to reduce the overall weight of the bike and improve riding efficiency, such as some high-end aluminum alloys.

2. But don't oversacrifice strength for light weight.

Corrosion resistance:

1.The material should be able to resist the erosion of rain, sweat, etc., to prevent rust and damage.

2. For example, properly treated aluminum alloy or stainless steel.

Cost factors:

1. Choose the right material according to the budget, some high performance materials may cost more.

2. But also balance price and quality.

Processing properties:

1. The material should be easy to process into complex disk shape and tooth shape.

2. Good machinability and formability.

Coefficient of thermal expansion:

It should be matched with the coefficient of thermal expansion of other components to avoid matching problems when the temperature changes.

Brand and reputation:

1. Choose well-known brands and material suppliers with good reputation.

2. Their products are usually rigorously tested and verified.

For example, 7075 aluminum alloy is often used in high-end bicycle teeth because it is strong and relatively light, while having good corrosion resistance and processing properties. Some race-grade bikes may opt for more expensive carbon fiber reinforced materials for extreme lightweight and high performance. For ordinary riders, the more cost-effective 6061 aluminum alloy or chromium molybdenum steel is also a common choice, they achieve a good balance between strength, weight and cost.
