How flexible is this cable? Would like to know minimum bend radius and expected number of flex cycles

Very flexible. I used it on my CNC and it constantly bends and flexes and it holds up great

Is this wire copper clad aluminum or is it stranded solid copper?

I'm pretty sure this is aluminum wire, not copper. And the wire's insulation is very soft and thick. It works but I swapped out for name-brand wire on my cnc.

Can i use this for hvac communication wire between air handlers and heat pump?

Don’t see why not. Follow the installation instructions, I’m sure they call out the required wire/gauge.

Can the wire be used to connect vfd to cnc sindle (1.5 kw) ? it uses 4 wires 3+1 ground

16awg would be better suited. 1500w motor on 110-120v would draw up to 12.5amps. If this cable is rated for 10 amps, it would not rated for that use. However, if using a 220-240v VFD and spindle, the power consumption would be half of that at 6.25amps. I would confirm this cable is rated for 300v (CL3) and not just 150v (CL2) The length of cable also makes a difference but I would recommend using this for at most NEMA 23 stepper motors, but not a 1.5kw spindle.
