The customer ordered different sizes of ruthenium coated titanium electrode samples, and we have already sent them out. We hope that the customer will receive it as soon as possible and test the effect of the product as soon as possible.
Part of the product appears blue because this part is not coated, and it turns blue after multiple sintering. As we all know, titanium will change color when it encounters high temperature, so this is a normal phenomenon.
If you need titanium electrode samples, please contact, we can provide proofing service, and the price of customized samples is equal to the bulk price.
