Lead-free solder is about 95% tin, and leaded solder is about 63% tin. So the world cost for tin determines the cost of electronics solder, especially as tin becomes much more expensive. The world cost of ordinary tin has skyrocketed to 213% of what it cost just 12 months ago, and the cost of Wonder Solder’s ultra high purity tin has skyrocketed to 262% of its cost 12 months ago.
We had to adjust Wonder Solder’s retail price by $15 on 2/27/21 (when the world was 5 months into this 12 month skyrocket). And now, another 7 months later, we reluctantly must do so again. The retail price of leaded solder now goes up the same $15 as before, and the retail price of lead-free must go up $20 (since it uses 95/63 = 150% the amount of tin).
Note that we’ve managed to control our total price increase, for this entire 12 month period, to merely 43% (for leaded thin solder as an example: $99/$69 = 1.43), even though world cost for our ultra-pure tin has skyrocketed to 262% during this same time period.
Remember that the true effective price of Wonder Solder is
still actually FREE !!!
The labor time and cost, that fast-flowing Wonder Solder saves you, compared to all other solders, still more than pays you back, for the few pennies that the solder costs for each solder joint, even with today's higher solder prices !!
