アルミニウムの材料安全性
Consideration of health and safety issues is important when customers are processing or using aluminium and aluminium alloys, and when scrap items are returned for recycling.
As aluminium and its alloys are inert and non-reactive when employed correctly, potential health and safety impacts are extremely limited. In addition to long-term experience with aluminium and its alloys in a wide variety of applications, the material has also been tested and reviewed for possible health effects.
The Company only stocks and sells aluminium and aluminium alloy grades that are standardised and proven to be safe for their recommended use. To ensure that all products sold by the company comply with the specified requirements, only suppliers whose production sites are certified in accordance with the ISO 9001 quality standard are used. In addition, the company’s sales and distribution Service Centres are also certified in accordance with this quality standard.

範囲 – RoHS & WEEE
WEEE指令（廃電気電子機器指令）として一般に知られるこの指令は、電気・電子機器メーカーを対象としており、主に2つの目的があります。
- 製造業者は、製品の寿命が尽きた後のリサイクルについても責任を負い、製造業者が達成しなければならない目標があります。.
- 電気・電子機器の製造工程における環境負荷物質の使用をなくすため、WEEE指令は、特定有害物質使用制限指令（RoHS指令）を参照しています。.
RoHS指令の主な目的は、4つの金属と2つの難燃剤の使用をなくすことです。これらの物質それぞれについて、電機・電子機器においては重量あたり0.1% を上限濃度値として許容します。
- リード
- カドミウム
- 水星
- 六価クロム
- ポリ臭化ジフェニル
- ポリ臭化ジフェニルエーテル
さらに、合金元素としての鉛に関する例外条項も含まれており、その最大許容濃度は以下の通りです。
- 0.35% by weight in Steels (including Stainless Steel)
- アルミニウム中、重量比で0.40%
- 銅合金中の% （重量％）
ステートメント
Our suppliers have confirmed that we do not have a problem in supplying material that fully conforms to the RoHS directive and as a Company we can thus make the following statement:
以下のレベルを確認できます：
- リード
- カドミウム
- 水星
- 六価クロム ポリ臭素化
- ポリ臭化ビフェニル (PBB)
- ジフェニルエーテル (PBDE)
are all below the maximum permissible levels stipulated in Chinese standard GB/T 26572 “Requirements of concentration limits for certain restricted substances in electrical and electronic products” (China RoHS), for all materials supplied by us.
The only exception to this is where a customer orders a grade of material for which the applicable Chinese, British, European or International material standard requires the level of one or more of these substances to exceed the limits specified in GB/T 26572. In such cases, the material will contain a value of each such substance in line with the requirements of the relevant material standard.
