Of 2 matters in RoHS,
Our products made by ourselves that is continuous casting, centrifugal castings, extrusions and ingot forms in bronze and brass is clear the limit on RoHS directive in usual conditions.
RoHS directive: It is Restriction of the use of certain Hazardous Substances in electrical and electronics equipment in Eu members. But as well as above products , for using automatic vending machine and automatic dishwasher etc. this directive have spread to plumbing and fittings etc. for a portable water.
| Certain hazardous substances(Extract) |
limit *1 | Exception |
|---|---|---|
| Hg(Mercury) | 1000ppm max | Having |
| Cr+6(Chromium 6) | 1000ppm max | Having for certain rust prevention. |
| Cd(Cadmium) | 100ppm max | Having for certain Cd plating. |
| Pb(Lead) | 1000ppm max | 4%wt under For copper alloys 1000ppm under For solder |
*1:Limit in WHO(In RoHS, such as limit is not indicated clearly) As of 2005.May

| Wrought | C3604 (Free cutting brass) |
61～120ppm |
*2:Regarding free cutting brass has already supplied under Cd=75ppm max.
*3:Having dezincification resistance.
Beside if there is a request of analysis for Cd ,we can enter it to material’s mill sheet.
But for Customized certain limit, we will produce products by a make to order.
