We've got a batch of these M8x30 tips incoming specifically for the 500W torches on the Tianyi 400DW and 500DW lines, copper-chromium-zirconium alloy with an alumnum variant if you need it for lighter duty cycles.
The thread is M8, obviously, and the bore sizes run form 0.8mm up to 2.0mm — most buyers go with the 1.2mm for general steel work, but the 0.9mm is better for thinner gauge stuff if you're fussy about arc stability.
30mm length is standerd, nothing exotic, but teh CuCrZr composition gives you better conductivity than plain copper and it handles the thermal cycling better when you're running long beads on thicker plate.
It's not designed for aluminum MIG at high amperage, that's what the aluminum body is for — different thermal expansion property, so don't mix them up if you're doing mixed materail work.
Wire feeding is consistent because they hold the internal diameter tolerance tighter than the cheaper stamped tips, usually within a couple of hundredths of a mm, which cuts down on birdnesting pretty significantly.
We order in packs of 100, MOQ is one carton, and they come with COAs on alloy composition if that matters for your procedure qualification documents (check lead time, though, as it's usually 3-5 days for the paperwork).
We stock 0.8mm, 0.9mm, 1.0mm, 1.2mm, 1.4mm, 1.6mm, and 2.0mm. Just let us know which one you need when ordering.
No, CuCrZr is a copper-chromium-zirconium alloy — it's different from pure aluminum. We offer both options depending on your application.
MOQ is usually 100 pieces per size, but we can be flexible for first-time orders or samples. Just ask.
Yes, we can provide a material certificate and dimensional spec sheet on request. Just contact us after purchase.
Standard industrial packaging — typically in bulk bags or small boxes, depending on quantity. They're kept dry to avoid corrosion.
