Now, Lab Test Your Production Parts for Low Temperature Black Oxide Finishing Free Offer from Birchwood Casey Tests Feasibility & Process Parameters

Eden Prairie, Minnesota: Birchwood Casey now offers fast turnaround on lab testing of iron, steel or aluminum production parts to establish feasibility for its low temperature black oxide processes.

Just send a few production parts to its testing facilities with brief information on the part material and its use. Birchwood Casey will process the parts with the appropriate low temperature blackening process and return the finished parts for evaluation. There is no cost or obligation. This is a FREE offer.

Test Blacken Iron And Steel Sample Parts
Widely used on many types of tooling and machine components, the TRU TEMP® low temperature black oxide process forms a durable, black magnetite finish that complies with Mil-DTL-13924 Class One and withstands 100 to 300 hours of salt spray. The non-polluting, low temperature process is much safer and simpler to operate than the boiling 290° black oxide. Finish appearance and corrosion protection is equal to or better than the high temp method. TRU TEMP part finishing takes just 25 minutes using a simple dip-tank process, and can be installed in any production plant with factory training.

Test Blacken Aluminum Sample Parts
Ideal for precision machined components, the LUMICLAD® electroless black oxide process forms a smooth, durable black finish that is .000060 inches thick (1.5 micron). This process provides a high quality method for blackening aluminum that doesn't involve the complexities and high costs of electrolytic black anodizing. The LUMICLAD finish will not shrink hole diameters or add measurable thickness to critical surfaces. In addition, the finish is electrically conductive, which makes it an ideal material for applications requiring a chassis ground. Rinse waters for the process are easily purified and recycled by means of an ion exchange system, so nothing enters the drain. LUMICLAD part finishing takes just 30 minutes for most aluminum alloys using a simple dip-tank process.

"This part testing offer is the best way to evaluate the feasibility and quality of our TRU TEMP and LUMICLAD finishes, at No Charge," reports Mark Ruhland, vice president of Birchwood Casey. "Our finishing experts will turn the sample parts around with recommendations in about 48 hours."
