I don’t want to sound too off the rails, but isn’t it considered hazardous to have regular contact with Aluminum? So something your hands rested on for potentially multiple hours a day may be of concern?
Let me know if I’m way off base here or if the anodized aluminum is different etc etc.
I’m not able to find anything about skin contact being poisonous other than the fact that some people are allergic to it.
This article on aluminum toxicosis mentions skin contact but only in the context that it would then go into your body. So working with aluminum shavings might be bad long term but as long as you don’t eat your keyboard I think you’ll be okay.
1xxx, 3xxx, 5xxx, and 6xxx aluminum alloys are widely used in food processing equipment - those alloys are considered to be safe for food contact by the National Sanitation Foundation (NSF - not the National Science Foundation) and other regulatory agencies, and is explicitly approved under NSF/ANSI standard #51 for food contact in all circumstances. Also everyone wraps their food in aluminum foil without issue, and uncoated aluminum is frequently used for peel-off lids, disposable trays and pans, and food utensils.
You should be more concerned with lead solder, which is widely used to solder together keyboards. According to the CDC. “Washing skin with standard soap and water is not enough to remove lead residues.”, and you should be using special lead-removal wipes such as D-lead after soldering. Or use gloves, or switch to lead-free.
Leaded brass alloys such as brass C360 is also frequently used to make items such as weights and badges (lead-free brass tends to machine poorly), though those surfaces are touched much less often than keycaps. Brass C360 contains around 2% lead, but much more is present on the surface as the machining cutters smear the lead on the surface.
Yes. Sadly that is absolutely true. Please don’t put yourself at any further risk!
ANYONE WHO IS IN DAILY DIRECT CONTACT WITH RAW OR TREATED ALUMINUM (Aluminium) PLEASE DO CONTACT ME IMMEDIATELY! WE WILL COLLECT AND PROPERLY DISPOSE OF ANY DANGEROUS ALUMINUM (Aluminium) PARTS AT NO COST! WE DO PREFER RAMA KEYCAPS AND 60% KEYBOARDS! BUT THATS NOT SO IMPORTANT.
There was a commotion some time ago about aluminum and alzheimer’s. There was an observation of aluminum deposits in the brains of alzheimer’s patients and there were subsequently many scare stories about aluminum being a cause of alzheimer’s. Just months later it was shown that it was the alzheimer’s which caused the aluminum deposits, not the other way around, but once people seize on an idea like that they never let it go. So the rumors persist to this day.
I see. Yes this is the rumor I have heard for some time. Sometimes mentioned when people rode bike handlebars with no grips or tape and of course deodorant with aluminum in it is something that get referenced.
If you’re handling solder every day for a few decades, there could probably be some valid concerns. If you’re soldering a few keyboards over the years, there is absolutely no reason to worry about using lead free solder, unless you’re eating it.
