Solder Bar, Lead Free, Sn96.3Ag3.7, Zero Halogen, Ultrapure

Ultrapure solder conforms to IPC/J-STD-006C and meets the strictest quality control standards in the industry. When purchased directly or through authorized distributors, purity is certified for each lot.

Storage, Handling and Shelf Life

Store in a dry, non-corrosive environment between 10°C and 40°C (50°F–104°F). Over time, the surface may darken or appear dull, which does not affect performance. Shelf life is two years from the date of manufacture for alloys containing more than 70% lead, and three years for other compositions.

Extruded Bar vs. Cast Bar Process

Wave solder / Selective solder “make up bar” is available in multiple sizes and shapes: Cast, Extruded, Anode, Ingot, etc. Regardless of shape, the purpose of the bar is to replace material in the pot that is removed during the manufacturing process or with the dross. The key is that the bar alloy is always the same no matter the shape of the bar.

With “conventional bar”, the most common shape is either Extruded or Cast. Alpha has historically manufactured Cast Bar. Extruding is a more expensive way to produce bar solder when compared with cast bar.

Is there any difference between Extruded bar vs Cast bar regarding the alloy?

No. Once an alloy is manufactured and ready for forming, the shaping process, whether, extruded or cast, has no impact on the alloy. Extruded and Cast meet the same technical requirements and specifications as they are the exact same alloy and come out of the same master pots.

Is there a difference in the shape between Extruded bar vs Cast bar?

Yes. Specific to the shape and size, there are small differences. Extruded bar has a more consistent size and shape as it is pressed through a die
