The distance between the top of the peak and the bottom of the valley is known as the depth profile.
Bead blasted aluminum sheet.
In the u s the depth profile is measured by mils thousandths of an inch in the metric system the micron one millionth of a meter is used.
You cannot use steel based blast medias with aluminum surfaces because steel media will impregnate the aluminum surface and create corrosion.
Key 1 for blasting aluminum blast media choice.
Steel shot or steel grit should be avoided.
Bead blast is a non directional finish that is uniformly textured and low gloss.
Pick a media a pressure a distance from the part and then blast the surface.
Any media can be used.
If you are blasting aluminum surfaces the abrasive media most often used is glass beads sodium bicarbonate or walnut shells.
Most shops say it s an art.
It can be found in applications ranging from anti slip surfaces industrial applications as a blasting media and as a raw material in refractories.
In effect the surface is blasted by the particles.
Can be coated with anti fingerprint coating for interior use.
When a sufficiently hard abrasive particle strikes steel it deforms the surface into a valley and pushes up peaks.
Decorative bead blasted black sheet in order to meet the international market demands we imported an automatic bead blasted production line which is applied to surface processing of stainless steel and aluminum sheets.
The consistency of the finish makes it excellent for panel to panel matching.
Bead blasting is essentially like a pressure washer that uses abrasive media instead of water.
Beadblasting is a process of altering the finish of a metal surface by subjecting the surface to a stream of glass bead sand or aluminum oxide particles delivered via high pressure.
Walnut shells sand and glass beads are common.
Steel is harder than aluminum and can create a surface profile which leads to corrosion.
Generally the basic material are 201 304 316l 430 441 443 and the surface would shown nice metal bright after finish.
One of the greatest keys to successfully blasting aluminum surfaces is choosing a sandblast media that is appropriate.
Its lower reflectivity makes it suitable for roofing applications.
The result is a matte non reflective finish.
