BLF Interest list for Very High Current Beryllium Copper springs Pt1(ENDED)

A pre-made sample of the same material even if not the exact dimensions costs them nothing. Just to be able to check the fit and finish and material. I don’t think anyone would hold it against you if you wanted to assume less risk and press them on this issue, I certainly would.

The only problem would be that since beryllium copper is not usually used for battery springs, there is a minimum order quantity going on.

I already have a spring with about the same dimensions, but only in phosphor bronze. That is the Kaidomain phosphor bronze spring in the picture.

Other than the material and 2.2x the electrical conductivity, there should be no difference between the two.

Nevertheless, I will ask again.

I really hope it goes well.

In for 30 of the smaller springs also.

May do more of both if we hit 2000(?) and see a price break.

If we do hit 2000pcs total, and I receive a sample from my supplier, yes, we will go above that amount, and see a price break.

BlueSwordM it looks to me like making 2000 large and 1000 small would be pretty easy to do, especially if there’s a bigger price break at 2000.
Might help if you contact them and find out the difference. I know for myself if they are cheaper each piece I’m going to up my order a little more. The main thing being if they are really good, everyone’s gonna want them. You really need to test samples even if there something they have surplus from another order. Just my two cents :wink:
Thanks for doing the GB. :+1:

I have already contacted them. It just takes time for them to respond.

And I will probably make 2000 big springs and 2000 small springs so they get even cheaper each

And when I get a sample, then the group buy is going to commence.

Also, thanks for the encouragement.

put me down for 10 big 10 small

The list has been updated again.

I hate to say it again, but I am absolutely impressed by the feedback of the community.

Also, what kind of name would you like for this spring?

I have thought about the BLF ULPS, being the BLF Ultimate High Power Spring.

Is that good name? What do you suggest?

Finally, I will test the conductivity of the spring when I get it, and how well it holds up under stress.

Name??? Why would you name a spring? :laughing:

Call it the ‘BSM/blf Special’…… :+1: … :wink:

Problem its that if you use a big spring ( if driver can like fet+1) in both sides theres will be too tight for the battery.

I preffer gold color, but its ok :wink:

In drivers that can use 9mm base spring theres will be better to use in driver side and in tail side also but its too tight So… what about a copy of fasttech carobronce spring but in Beryllium Copper and gold plated?

I think its a very usefull size for both: driver and tailcap.

Question: the elasticity of this Beryllium Copper 38% is good? are not very soft?

Thanks for this BlueSwordM :wink:

1. Hmm I have not thought about a copy of the Fasttech Carobronze spring, but with BeCu 38% IACS.

2. The elasticity of 38% IACS Beryllium Copper is better than 45% IACS as it is less rigid, and has a lower chance of deflection and collapsing.

You are welcome :wink:

Also, guys, I do not know if I understood it well from one of my suppliers or not.

But APPARENTLY, I hope I am not wrong, but holy crap, I hope I understand it well, the supplier said that 2000 big springs of Beryllium Copper 38% IACS would cost, with DHL shipping:

350$US. 350 AMERICAN DOLLARS. NOT CANADIAN DOLLARYDOOS.

350$US. The cost price per spring sold, with shipping, could probably be lower than 0,30$US!

The price IS NOT FINAL

I will check with my supplier if the price is correct or not. If it is, then hallelujah!

Also, BTW, they have accepted to send 10pcs sample for 100$ US. So as expected.

I will test the samples when they get there, and see what kind of resistance they have, and comparing them to djozz’s springs testing.

Edit: The sample will add to the final price:

350$US+100$US = 450$US

Still, that is a crazy good price.

This is sounding better & better BlueSwordM!! Thank you again!! :beer: . :slight_smile:

Yeah it is getting better and better.

If that price is correct and the springs are good, you should calculate the costs for those samples within the final price.
It’s only a small increase.

Thank you for the mention, I will add it to the post.

I think that even though were getting charged crazy money for the samples, it’s definitely worth while. If the price is $350 for 2k and not per thousand that still leaves us getting a great deal.

I have only asked for 2000pcs though. Not 3000pcs, which includes the 1000 small springs. I do wonder what the price will be then.

We are at 1131 big springs and 592 small springs.

Interested in 10 big an 10 small springs
