Cov txiaj ntsig zoo thiab qhov tsis zoo ntawm Copper pwm
Zoo heev Thermal conductivity
Tooj liab cov thermal conductivity (kwv yees li 380-401 w / (map k)) yog qhov ntau dua li ntawm txhuas alloys (kwv yees li 100-230 w /, (m)). Nws tuaj yeem hloov cua sov sai li sai tau hauv cov pwm, ua rau nws haum rau cov ntawv thov uas yuav tsum tau ua kom sai li kub ... tsis kam. Piv txwv li:
Kub khiav ntxig thiab cov cheeb tsam txias txias rau cores / kab noj hniav hauv kev txhaj tshuaj pwm (piv txwv li, rau nyias- palled yas seem thiab cov khoom sib xyaw);
Cov kab ke hauv zos hauv qhov siab - kev pheej hmoo thaj tsam ntawm tuag}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} cast def deformation vim kev kub dhau mus vim kev kub dhau.
Zoo hluav taws xob conductivity
Qee cov pwm tshwj xeeb pwm (piv txwv li, EDM cov hluav taws xob thiab hluav taws xob ua hluav taws xob, tshwj xeeb yog tooj liab thiab cov khoom tooj liab) cov khoom nyiam.
Zoo toughness thiab muaj zog qaug zog tsis kam
Tom qab kev kho mob kev laus, beryllium tooj liab tuaj yeem ncav tes ua kom muaj zog tshaj li 1000 MPa. Nws cov tawv yog zoo dua rau qee cov alloys aluminium, ua rau nws cov kev thov rov qab tab sis cov khoom seem qis (piv txwv li cov hnyuv ntxig hauv cov pob zeb me me). Qhov tsis zoo: Tsawg tawv thiab hnav tsis zoo. Copper's hardness (beryllium copper is approximately 30-45 HRC, while red copper is only 30-40 HB) is much lower than that of high-strength aluminum alloys (such as 7075 aluminum alloy, which can reach 150-180 HB, approximately 12-15 HRC). Nws yog qhov ntxim rau kev hnav thiab deformation thaum raug kom ntev kev sib txhuam lossis kev kub siab, ua rau muaj sia luv dua.
Nws tsis haum rau siab - thauj pwm pwm (xws li tuab tuab stamping thiab tuag loj-}}} Castting pwm).
Tus nqi siab thiab siab ntom: Tooj (tshwj xeeb tshaj yog 3-5 lub ntom ntom) yog ntau tshaj peb zaug ntawm txhuas alloys (2.7 g / cm³). Nws tsis haum rau cov pwm loj (raws li nws nce cov khoom siv thiab cov nqi).
Kev ua haujlwm siab: tooj lub siab ua kom zoo ua rau nws nquag mus rau "sticking" thaum lub sijhawm txiav, ua rau cov cuab yeej tseem ceeb hnav. Nws txoj kev ua tau zoo hauv kev siv cov duab ua ke yog qis dua li cov alloys alloys.
