This is the portion I ws able to copy and paste. There was a small chart showing the compounds that I could not pick up. I had tought I saved it all but not so.

some of you may know who follow this thread very closely, this last week the case manufacturers had issues with their latest batch of CuSn8 bronze exhibiting impurities during the finishing stage. I cant tell you how happy I have been with the manufacturer though, they contacted me immediately and not only presented me with this news, but also with a few very surprising and welcomed solutions. They of course did not want to be using sub-par bronze for our cases, and were concerned first that if this latest batch of CuSn8 was exhibiting impurities in the finishing stage, that they also worried that perhaps the first batches were somehow compromised as well. Talk about 1 bad apple spoiling the bunch. Of course no one wants to waste time doing a lengthly recall, and because they are warrantying these parts for 1 year, they want to do it right the first time around. The best way around this? "Well of course, its to use a higher quality, and more technically advanced bronze alloy." Of course, I agree . They offered immediately to create a new set of cases using a higher quality, more tech bronze. The differences in the composition are small, but the result is a harder, more resistant bronze alloy. I believe this is the same concept behind Aquadive's bronze mixture. For example, here is a bronze comps they offer as a variant of CuSn8 :

This is where the chart would not copy......

You end up with an alloy that is more technically advanced and resistant as a result of the added elements iron and nickel, even in such small amounts. These mixtures are more expensive, but the manufacturer is offering to do this as a free upgrade!! These are in-house alloys, they want to proceed only using alloys they have their own hand in creating. We had always anticipated a may shipping date, and our manufactures are aware of the time frame. Its working out to have a minimal impact on the Olivier time frame, if at all. Its great to know how seriously they are taking our limited order in the grand scheme of things!

Is this the chart ?

It may be Johnny, I saved the portion I posted but must have erased the original email/ Sorry, it did look similar but not sure about the #'s used.

sorry to hear this,and I guess Roland does not want to reply here,but then he probably knows we know more than we let on...
what everyone will be getting is probably what he had to begin with...and that was not CuSn8... this new alloy is a copper alloy,not bronze from what I have been told,and not an upgrade at all... all this after he repeatedly swore in this thread that his watches in hand were cuSn8...

Really had hoped not to have to deal with this BS, but as the saying goes,
If its to good to be true it probably is

Hey Guys!

Very sorry for the late reply, but this forum does not email me when posts are made to threads. The change in the bronze alloy is extremely small, and still constitutes a CuSn8 alloy. The additions to the alloy are around a half of 1 percent to the total mix, in fact, other CuSn8's are most likely mixtures like this as well.

Here is the Chemical composition of CuSn8:
Chemical Composition:
Sn: 7.50-8.50%
P: 0.03-0.35%
Zn: 0.20% Max.
Fe: 0.10% Max.
Pb: 0.05% Max.
Zn: Balance
CuSn8 - UNS.C52100 Phosphor Bronze Alloys, which is a 8% tin bronze distinguished by a very good combination of strength and electrical conductivity. It is used for connector and current-carrying springs in contacts. Among the 4-8% tin bronze C52100 exhibits the lowest electrical conductivity, the highest reachable strength is significantly higher than C51100 and C51000 and C51900. By means of an additional further tempering after the cold forming process the bendability can be further improved.
In addition, it has better corrosion resistance and good sliding properties. C52100 is used for springy components and sliding elements when increased strength and wear-resistance are required.

From what I read, in general most Bronze is defined by being a metal alloy, with it's primary composition that of Copper... CuSn8 would then be also a copper alloy. I think we are now just splitting hairs..

Hey Oscar!

I would definitely have appreciated a PM! The changes to the alloy are slight, but nothing but beneficial.

Thank you Craustin1! Perfect example of alloys that can be CuSn8, but comprise of also additional elements, in that alloys case Iron, lead, and a very small amount of zinc.

Or another example of CuSn8 with added iron and nickel.

Roland,
I'm not a chemist, so in simple speak , are you saying the main materials used in Cusn8 remain the same but they are adding small amts of the additional irons?
