Would you trust a Temu 80A electrical connector?

Without full metallurgy tests it's hard to say exactly what alloy this electrical connector is made of. The attraction of a strong neodymium magnet was very slight, even with the outer plating and nearby steel screws removed. I'll guess a brass alloy with a nickel plating. A subsequent test on random brass plumbing fittings also showed a very slight attraction of the same magnet.

Brass is technically an alloy of copper and zinc, with the colour being affected by the ratio. With the cost of copper these days, it's no surprise that it looked a light golden colour, suggesting more zinc than copper. Then again, I'm sure there are probably cheap alloys being made that look like brass to cut costs.

In this application the chunkiness and very close vicinity of the coupled wires is probably a benefit for the application of acting as a single pole power distribution block.

China has a huge manufacturing industry, so it's no surprise that they have a lot of machine components at fairly low prices. This block cost £3 which compared favourably with a similar distribution block from a UK seller at £12.

I'd consider this block for personal panel projects, but not for an industrial application where the cost of machine down-time makes the use of prominent brand items more important.
