Indium Bar Solder BAROT-06759 Lead Free SN995 | 25lb box
Indium BAROT-06759 — SN995 Lead-Free Bar Solder, 25lb Box (18 Bars)
Sold in 25 lb boxes (18 triangular bars per box).
Indium BAROT-06759 is a cobalt-doped SnCu lead-free bar solder alloy (SN995: 99.5Sn/0.5Cu/Co) designed as a low-cost, low-maintenance alternative to SAC305 and popular low-silver lead-free alloys like Sn100C. The cobalt doping provides lower dross formation, smoother and shinier solder joints, and less copper erosion than SAC305 and standard SnCu-based alloys. Compatible with existing SnCu-based alloys — can be added to Sn100C pots without adverse reactions. Ideal for wave soldering operations seeking to reduce alloy cost and pot maintenance without sacrificing joint quality.

Key Features
- Low cost — no silver content; significantly lower alloy cost than SAC305
- Low dross formation — lower dross than SAC305 and standard SnCu alloys, reducing waste and pot maintenance frequency
- Low maintenance — does not require frequent solder pot analysis or pot balancing alloys
- Smoother, shinier joints — cobalt doping improves joint appearance vs. SAC305 and SnCu alloys
- Less copper erosion — lower copper dissolution rate than SAC305, extending pot life and reducing board pad erosion
- SnCu compatible — can be added to existing Sn100C or other SnCu-based pots without adverse reactions
Frequently Asked Questions
What is the difference between SN995 and SAC305 for wave soldering?
SAC305 (96.5Sn/3.0Ag/0.5Cu) contains silver, making it significantly more expensive than SN995 (99.5Sn/0.5Cu/Co). SN995 eliminates the silver cost while the cobalt doping provides lower dross, smoother joints, and less copper erosion than SAC305. For cost-sensitive wave soldering operations where SAC305 performance is not required, SN995 is a compelling lower-cost alternative.
How does SN995 compare to Sn100C?
Both SN995 and Sn100C are cobalt-doped SnCu lead-free alloys with similar compositions and performance characteristics. SN995 is compatible with Sn100C pots — it can be added to an existing Sn100C wave solder pot without adverse reactions, making it a practical replenishment or transition option for Sn100C users.
Why does SN995 produce lower dross than SAC305?
The cobalt doping in SN995 reduces the oxidation rate of the molten solder, which is the primary mechanism of dross formation. Lower dross means less alloy waste, less frequent pot skimming, and lower overall operating costs in wave soldering production.
Is BAROT-06759 available in cored wire format for rework?
Yes — Indium SN995 alloy is available as cored solder wire for hand soldering and rework applications in addition to the bar solder format. Contact MTE Solutions for SN995 cored wire part numbers and availability.
How many bars are in a 25lb box?
Each BAROT-06759 25lb box contains 18 triangular bars. The triangular bar shape is standard for wave solder pot loading and is compatible with most wave soldering equipment bar feeders.
