Die casting light weight crank pulley Review

Some people asking me,why that is some light weight Crank pulley selling on Rm100+

1. Please look Carefully,the surface is powder coating BLUE/RED,because they are not using CNC machine to develop the pulley,So they use powder Coating to cover the rough surface.

2. They are using die casting with Mixed,Aluminium,We will never know what type of material they use,how many % of Alloy and how many % of steel or any other material (So that is not consider Pure AlloyPulley)
Example:

3. Because die casting Pulley are develop by Unknown mixture material,So that is risky to use die casting Pulley ,Because it might,cracked,Unbalance weight,over light weight.

4. You pay what you get,because die casting can be very cheap by using lousy Mixture.
