Aluminiyning material xavfsizligi
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.

Doira – RoHS va WEEE
Elektr va elektron chiqindi uskunalar bo'yicha direktiva, odatda WEEE deb ataladi. Bu elektr va elektron uskuna ishlab chiqaruvchilarga mo'ljallangan bo'lib, ikkita asosiy maqsadga ega:
- Ishlab chiqaruvchilar mahsulotlarning foydalanish muddati tugagach ularni qayta ishlash uchun ham mas'ul bo'ladilar va ular bajarishi kerak bo'lgan maqsadlar mavjud.
- Elektr va elektron uskunalarni ishlab chiqarish jarayonidan atrof-muhitga sezgir moddalarni foydalanishni bartaraf etish. Buning uchun WEEE direktivasida Xavfli Moddalarni Cheklash (RoHS) direktivasiga murojaat qilinadi.
R0HS direktivasi asosiy maqsadi to'rtta metall va ikkita yong'inga qarshi moddadan foydalanishni yo'q qilishdir. Ushbu moddalarning har biri uchun elektr va elektron uskunalarda og'irlik bo'yicha maksimal 0,11 TP3T konsentratsiya qiymati ruxsat etiladi:
- Yetakchi
- Kadmiy
- Simob
- Geksavalent xrom
- Polibromlangan difenillar
- Polibromlangan difenil efirlari
Bundan tashqari, istisnolarni qamrab oluvchi qo'shimcha band mavjud bo'lib, u qotishma elementi sifatida ishlatilganda maksimal konsentratsiya qiymatlari quyidagicha bo'lgan qo'rg'oshinni o'z ichiga oladi:
- Po'latlarda (zanglamaydigan po'latni ham o'z ichiga olgan) og'irlik bo'yicha 0,351 TP3T
- Alyuminiyda og'irlik bo'yicha 0.40%
- Rux qotishmalarida og'irlik bo'yicha 4.00%
Bayonot
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:
Biz quyidagi darajalarni tasdiqlay olamiz:
- Yetakchi
- Kadmiy
- Simob
- Geksavalentli xrom polibromlangan
- Bifenil (PBB) polibromlangan
- Difenil efir (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.
