The semi-cone angle of a cone clutch is made 12.5° for specific reasons. This angle is chosen to ensure optimal engagement and disengagement of the clutch. A smaller angle would result in a higher engagement force, making it difficult to disengage the clutch smoothly. On the other hand, a larger angle would reduce the engagement force, leading to slippage and reduced power transmission efficiency.

Now, let's discuss the desirable properties for good friction material in a clutch. There are several important properties to consider:

1. High coefficient of friction: The friction material should have a high coefficient of friction to ensure effective power transmission and prevent slippage.

2. Good wear resistance: The friction material should be able to withstand the high pressures and temperatures generated during clutch operation without excessive wear. This ensures a longer lifespan of the clutch.

3. Stable friction characteristics: The friction material should maintain consistent friction performance over a wide range of operating conditions, including temperature and pressure variations.

4. Low fading: Fading refers to a decrease in frictional performance under high temperatures. A good friction material should have low fading characteristics to maintain reliable clutch operation even under extreme conditions.

5. Low compressibility: The friction material should have low compressibility to ensure a quick and precise engagement of the clutch.

6. Compatibility with mating surfaces: The friction material should be compatible with the mating surfaces of the clutch, ensuring smooth engagement and disengagement without excessive wear or damage.

By considering these desirable properties, manufacturers can select the most suitable friction material for a cone clutch, ensuring optimal performance and durability.
