Fine Needles And Needle Forms

One of our specialities is processing tubes made to exact high tolerances using a wide range of metals and alloys. Tubes with diameters between 0.5mm and 50mm are supplied, with thin wall tubes as thin as 50 microns (0.050mm). Whilst the majority of our products are made from stainless steels, we also supply thin-wall tubes made from titanium, brass, copper, phosphor bronze, nickel silver and other precious metals,

Our tubes can be supplied in long lengths, cut to length or with additional features. We can also supply the tube as part of an assembly, comprising machined components laser welded or vacuum brazed to the tube.

Processes include swaging, flaring, bending, cutting and finishing tube to our customers’ designs.

Standard Size Range

The table shows the standard sizes for hypodermic needle tubing which is made from A.I.S.I type 304 austentic stainless steel. Originally intended for surgical purposes, its metallurgical properties and the wide range of sizes have lead to increasing use in instrumentation, electronics, nuclear physics and other industries needing precision and corrosion resistance.

Please see below for a table of our Standard Size Range.

What We Can Supply

We can supply tubing or wire in stainless steel, nickel alloys, light alloys, bronze and various rare metals in random lengths or cut accurately to length, square and burr free. We can turn it, mill it, grind it, bend it, rotary swage it, polish, drill very small holes in it, soft or silver solder it or micro weld it. We also have EDM capability for very small or irregular shaped holes.

If the size you want is non-standard it can be made by manipulating standard tubing or by special drawing Contact us today for more information.
