采购商询盘内容

I'm looking to procure several graphite plates with specific dimensions and properties. The first type required is a set of 6 plates measuring 490x40, along with another set of 6 plates sized 450x20. It's essential that these plates meet particular technical specifications. The density should be around 1.68 g/cm³, and I'm looking for a low electrical resistivity range between 7 to 9 µΩ·m. Additionally, the thermal conductivity at 100 °C must be approximately 121.1 W/m·K. Other critical parameters include a coefficient of thermal expansion at -600 °C of 5.46 × 10⁻⁶ /°C, a hardness level of 22 HSD, flexural strength of 19 MPa, and compressive strength of 38 MPa. Please ensure the porosity is around 17%, with ash content not exceeding 1000 PPM and a purity level of 800 PPM. The grain size should be about 0.5 mm. Looking forward to your prompt response!
我想采购几块特定尺寸和性能的石墨板。首先需要一组6块490x40的石墨板，以及另一组6块450x20的石墨板。 这些板材必须符合特定的技术规格。密度应在1.68 g/cm³左右，电阻率应在7至9 µΩ·m之间。此外，100 °C 下的导热系数应约为 121.1 W/m·K。其他关键参数包括：-600 °C 下的热膨胀系数为 5.46 × 10⁻⁶ /°C，硬度为 22 HSD，抗弯强度为 19 MPa，抗压强度为 38 MPa。请确保孔隙率约为 17%，灰分含量不超过 1000 PPM，纯度为 800 PPM。晶粒尺寸应约为 0.5 毫米。期待您的及时回复！
