What alloy is used for petrol pump alloys? It obviously does not produce a spark when clunked into the car's petrol tank by some heavy-handed buffoon. Maybe the Darwinian theory could be allowed to take its course.....

In most cases it's pure aluminium but I have read that sometimes aluminium alloys are used for this purpose:

Bioalcohol fuel pumps in the USA tend to use nickel-plated aluminium nozzles which apparently are more efficient at resisting fuel cross-contamination. I saw this at first hand myself a few months ago when I hired a biofuel vehicle in Oahu for the first time in my life. I think the same type of nozzles are used for biofuel in the UK.
