Shades of gold

Post  Jason_WI on Sat Feb 04, 2012 1:05 am

Cleaning the 010 and the 020 lot I just got I noticed 4 different shades of gold cases. From dark gold to almost pinkish gold when its in the right light.

Any way to tell the age by the color or just lot variation from manufacturing.

4 different shades next to a silver case.

What causes the fade? Sunlight, heat, chemical reaction?

Color anodizing can fade due to intense UV light exposure and wear. The anodizing process honeycombs the surface of the aluminum (aluminum oxide actually grows out of and into the surface) and allows the infusion of the dyes. The length of time in the dye bath can determine the deepness of the color, as does the dye concentration and amount of porosity. After anodizing and dyeing, the surface must be sealed to avoid leaching of the color. Consequently, anodizing depth, color immersion and concentration and sealing are all variables that will affect the overall final product. Variation in any of these can yield a different shade to start; wear and UV exposure will change it over time.

I have an older BW that has the color worn off part of the spinner due to stopping the engine with my fingers when it started backwards.

My Black Widow spinners are all pink, but that's from from gopher diving. All my planes are trained to hunt gophers, except Li'l Satan, amazingly, she's never been lawn boring. Thank goodness.

I noticed it last month on my tee dee.020's

I got 2 of 1987, which where much lighter. And 6 with from 89, which where more dark. I think there is a diffrence between each run of anodizing.

They are all NIB and did not see any sunlight after leaving the factory!
