The Excelta Corporation 7-TA 4-Star 4.5" Titanium Alloy Tweezers are great for all solder applications; solder will not adhere to the tip. Titanium tweezers are also heat resistant to 430 Deg C, which makes them perfect for today’s "no lead" soldering temperatures. They are completely non-magnetic (zero magnetic retentivity) and highly resistant to most common acids. As an added feature the titanium alloy is very lightweight compared to Stainless Steel. Made in Switzerland.
