Merry Christmas / Website DNS

    Wishing everyone a Merry Christmas and Happy New Year!
    We have new items coming into 2016. CNC Toy and r/c car parts will be produced, A new website (probably www.titaniumautobolts or will be opened to help with the titanium bolt end of the business and some new local services like bead blasting and welding will also be done in the shop.
    The website DNS servers are down for Christmas and the website might be offline for a day or so until resolved. This is from the server end and is a global server problem. Since it's Christmas it might take more time to resolve. Sorry about this, please check back.

Precision Billet MTB Levers!

    Just completed anodizing on some of the new levers for 2016. These retro type levers are heavy duty and are made for twist grip type shifters. 10mm adjuster for impact resistance, also ava. in titanium.
    Hardware is titanium and aluminum. fits standard bars. These will be posted on the website shortly.

Anodizing Tips: Effects of Alloys on Aluminum

Below is a basic chart on how various metals react with aluminum in anodizing.
This is accurate based upon our results.

Iron Reduces the brightness even in small amounts. Its addition to pure aluminum leads to dark grey or black streaks, especially when high iron to silicon ratio
Silicon At 5% level alloys, dark grey or black tones are obtained.
Copper Up to 2% can give alloys with a clear protective coating. At higher level, anodizing becomes more difficult and the coating is softer and with less protective value
Chromium At 0.3% leads to coatings which are yellow in color.
Titanium Reduces the brightness, as iron, but is added to produce finer grains
Magnesium Can give clear colorless coatings up to 3%, because magnesium oxide has a reflective index (1.736) very near to that of aluminum (1.69)
Manganese Up to 1%  may anodize to clear silver, grey brown or mottled according to production process and particles size of the constituents. With thicker anodic films, manganese contents of 0.3-0-0.5% give quite brown anodic oxide coatings on all the alloys.
